Taming the CORS Beast

CORS errors are essential for web security, protecting users and data integrity. Developers can prevent these issues by understanding their causes and using proper server-side configurations or proxy solutions. Emphasizing security and following best practices ensures a reliable web application environment

In this dynamic online world where web browsers are ubiquitous, protecting user data and preventing unauthorized access is crucial. CORS controls how browsers handle requests from a web page to resources hosted on a different site. One of the main security measures used by browsers is Correspondence (CORS). However, developers often encounter problems when setting up CORS, especially when integrating with external APIs or storing resources from multiple domains.

What is CORS?

    The CORS feature in web browsers ensures that requests to resource from a different domain are handled differently from those sent from the original web application pages. This feature can be challenging to implement for developers due to how it affects the integration of external APIs and fetching resources.

Why Does CORS Errors Occurs?

   CORS errors occur when a web application hosted on one domain tries to access resources (like APIs) hosted on another domain that has different origin policies. It may also happen if there is a difference in the port and the protocol.  Browsers enforce these policies by blocking such requests unless the server explicitly allows them through CORS headers.

Common Scenarios Leading to CORS Errors:

API Integration: When a front-end application (running on `https://sample-example.com`) is tries to fetch data from an API (hosted on `https://sample-api.example-api.com`), the browser checks if `https://sample-api.example-api.com` allows requests from `https://sample-example.com`. If not configured correctly, CORS errors will occur.

Subdomains: Even requests between subdomains (`https://sample-app.example.com` to `https://sample-api.example.com`) can trigger CORS errors if not properly configured.

How to Resolve CORS Errors: 

1. Server-Side Configuration:

 -- CORS headers: Improved the server hosting API to include CORS headers in responses. These headers define resource permissions ('Access-Control-Allow-Origin'), permission methods ('Access-Control-Allow-Methods'), and other CORS-related settings. If your API is accessible from any source, you can set 'Access-Control-Allow-Origin: *' to allow requests from any source. However, due to security concerns, this method must be used with caution.

2. Proxy Servers: 

- Reverse Proxy: Use a reverse proxy on your server to route API requests through the same domain as your frontend application. This effectively bypasses CORS restrictions since requests are made from the same origin.

3. Preflight Requests: 

- OPTIONS Requests: For requests that might trigger CORS, browsers may send a preflight request (OPTIONS) to the server to check if the actual request (GET, POST, etc.) is allowed. Ensure your server responds correctly to OPTIONS requests with appropriate CORS headers.

4. Client-Side Handling: 

- Fetch API: When making requests using JavaScript's Fetch API or XMLHttpRequest, handle CORS errors gracefully. You can catch these errors and provide meaningful feedback to users or retry the request if possible.

5. Development Environment: 

- Browser Extensions: During development, browser extensions like CORS Everywhere or modifying browser settings can temporarily disable CORS restrictions. However, these should not be used in production environments.

Conclusion:

CORS errors are essential for web security, protecting users and data integrity. Developers can prevent these issues by understanding their causes and using proper server-side configurations or proxy solutions. Emphasizing security and following best practices ensures a reliable web application environment.

can we hear about the bug that in your opinion is the most important in nature? :3

You have subscribed to DAILY BUG FACTS

🪲

TODAY'S FACT IS

Did you know that the European Honey Bee (Apis mellifera) is the most common honey bee worldwide but is not native to the American continents?

These bees will visit many species of plant in a day making them good general pollinators, but not as effective as a specific pollinator (this is also a reminder that it is important to have plants native to your area to invite native and specialized pollinators).

These honey bees are excellent communicators with each other, speaking both with pheromones and 💃dancing. These communications can be used for defense of the hive, recognizing a member of the colony, directing to pollen, or countless other things.

[what-if-it-was-a-warrior-cat]

This is my aunt's cat, Apis! She has 2 kittens here because this is the only photo I have of her lol.

I am Swedish and Apa is Monkey and the -is suffix is kinda like adding an y at the end of a word to make it cute (doggy, Foxy, Kitty)

She has had like a billion litters of kits and is like 13 years old. Very kind and sweet, an inside/outside cat but is also really cool. Once we found a claw in my dog (who hates cats) nose because she bothered Apis. She cuddled my hand even though I was like right by her kits, so very trusting to humans.

Apis -> Siltbrook

Role: Queen (permanent)

Siltbrook, while nowadays prickly with most cats, is gentle as a feather with the clan's kits. Although she may not show it most of the time, she trusts all of her clanmates as if they were her family. She chose to stay in the nursery permanently after she had her second litter, as she figured it would be a lot more convenient for her. She's old enough to be an elder, but refused to retire, even when the leader gently encouraged her to take even just a little break from watching over the clan's kits. She says that she would 'sooner stick her head in a badger's den' than retire. Her favorite prey is newts!

the social stuff can be mitigated... this can't, we're so screwed globally :|

[jaffacake6]

If anyone's used the Tumblr API and knows it decently, drop me a message please - I'm trying to build an accesssibility tool to search for existing image IDs in a given post, but can't seem to get all the reblogs for the post, just a few of them.

And the API documentation ain't great.

[ihasafandom]

Anyone know how to use AutoHotkey with tumblr?

I wanna make a hotstring that'll paste in OP's blog name, but I am an amateur and have no idea how to do more than check that the focused page is actually tumblr and make the hotstring itself with an empty %OPGet% variable. What I probably need is: determine what post is hilighted (this must be a thing since tumblr can navigate with keys already) grab the post contents. find the post's OP link. strip the name out of the url with regex return the name to the variable.

Any help?

How the IP Proxies API Solves Highly Concurrent Requests

With the rapid growth of Internet services and applications, organizations and developers are facing increasing challenges in handling highly concurrent requests. To ensure the efficient operation of the system, API interface becomes an essential tool. Especially when dealing with highly concurrent requests, Rotating IP Proxies API interfaces provide strong support for organizations. Today we'll take a deeper look at the role of the Rotating IP Proxies API and how it can help organizations solve the problems associated with high concurrency.

What is the Rotating IP Proxies API interface?

Rotating IP Proxies API interface is a kind of interface that provides users with network proxy services by means of Rotating IP address allocation. It can schedule IP addresses in different geographic locations in real time according to demand, which not only helps users to access anonymously, but also improves the efficiency of data collection, avoids IP blocking, and even carries out operations such as anti-crawler protection.

With the Rotating IP Proxies API, organizations can easily assign IP addresses from a large number of different regions to ensure continuous and stable online activity. For example, when conducting market research that requires frequent visits to multiple websites, the Rotating IP Proxies API ensures that IPs are not blocked due to too frequent requests.

Challenges posed by highly concurrent requests

Excessive server pressure

When a large number of users request a service at the same time, the load on the server increases dramatically. This can lead to slower server responses or even crashes, affecting the overall user experience.

IP ban risk

If an IP address sends out frequent requests in a short period of time, many websites will regard these requests as malicious behavior and block the IP. such blocking will directly affect normal access and data collection.

These issues are undoubtedly a major challenge for Internet applications and enterprises, especially when performing large-scale data collection, where a single IP may be easily blocked, thus affecting the entire business process.

How the Rotating IP Proxies API solves these problems

Decentralization of request pressure

One of the biggest advantages of the Rotating IP Proxies API is its ability to decentralize requests to different servers by constantly switching IP addresses. This effectively reduces the burden on individual servers, decreasing the stress on the system while improving the stability and reliability of the service.

Avoid IP blocking

Rotating IP addresses allows organizations to avoid the risk of blocking due to frequent requests. For example, when crawling and market monitoring, the use of Rotating IP Proxies can avoid being recognized by the target website as a malicious attack, ensuring that the data collection task can be carried out smoothly.

Improved efficiency of data collection

Rotating IP Proxies API not only avoids blocking, but also significantly improves the efficiency of data capture. When it comes to tasks that require frequent requests and grabbing large amounts of data, Rotating IP Proxies APIs can speed up data capture, ensure more timely data updates, and further improve work efficiency.

Protecting user privacy

Rotating IP Proxies APIs are also important for scenarios where user privacy needs to be protected. By constantly changing IPs, users' online activities can remain anonymous, reducing the risk of personal information leakage. Especially when dealing with sensitive data, protecting user privacy has become an important task for business operations.

How to Effectively Utilize the Rotating IP Proxies API

Develop a reasonable IP scheduling strategy

An effective IP scheduling strategy is the basis for ensuring the efficient operation of the Rotating Proxies API. Enterprises should plan the frequency of IP address replacement based on actual demand and Porfiles to avoid too frequent IP switching causing system anomalies or being recognized as abnormal behavior.

Optimize service performance

Regular monitoring and optimization of service performance, especially in the case of highly concurrent requests, can help enterprises identify and solve potential problems in a timely manner. Reasonable performance optimization not only improves the speed of data collection, but also reduces the burden on the server and ensures stable system operation.

Choosing the Right Proxies

Purecode | Backend Proxy

Consider making API requests through a backend server where your API key is stored and not exposed to the frontend. This way, the API key is kept hidden from the client-side, reducing the potential for unauthorized access.

Apache Kafka became the de facto standard for data streaming. However, the combination of an event-driven architecture with request-response APIs is crucial for most enterprise architectures. This blog post explores how Tinybird innovates with a REST/HTTP layer on top of the open source analytics database ClickHouse in the cloud. Integrating Kafka with Tinybird, the benefits of fully managed services like Confluent Cloud, and customer stories from Factorial, FanDuel and Hard Rock Digital show why Kafka and analytics databases complement each other for more innovation and faster time-to-market. The post Apache Kafka and Tinybird (ClickHouse) for Streaming Analytics HTTP APIs appeared first on Kai Waehner.

greedy but I would love some unofficial semi-official guidance on api request rate without getting an unusual behavior flag... and for it to be like 500ms (or less, less would be cool obv)? that's about how fast I paginate by just holding down the end button on the website so it feels reasona—

—ah interesting, I retested this to make sure that's true and it's only kind of true now? it is on my own blog but I think the virtual scroller stuff has a pretty significant performance impact and it's somewhat slower on dash (honestly it kind of looks like smooth scrolling is causing every post to dynamically rerender which is pretty horrible to watch).

well whatever anyway my own blog still counts as a real world use case.

I think actually documenting official rate limits (per endpoint or otherwise) doesn't really feel appropriate but xkit rewritten's "one whole second between requests" feels on the super-conservative side. I promise I'll fire them sequentially if you let me go lower so if the server is slow to respond it naturally reduces the rate <3
