AJAX calls experience delays when made in rapid succession

When running an app on my laptop that makes 7 AJAX GET requests simultaneously to a single PHP script, everything works perfectly with all requests returning the desired results.

However, after moving the script to a Windows Server running Apache and PHP, this process encounters issues when making the same 7 AJAX requests. Interestingly enough, if each request is made individually, they all succeed. It seems like there's some obstacle preventing me from executing all 7 requests at once.

I'm curious as to why this discrepancy occurs. Are there specific configuration variables in the PHP.ini and httpd.conf files that could shed light on this issue?

Any insights would be greatly appreciated.

Answer №1

It appears that the issue might be related to the browser's limitations.

Most browsers impose a limit of 2 concurrent connections when communicating with the same server.

After moving your application to the server, there may have been additional latency causing overlap in AJAX requests that were previously served quickly on localhost.

Answer №2

To prevent an overload of requests, the server could be using a throttler to limit the rate at which they are received.

Answer №3

element, there may be restrictions in your Apache configuration that control the amount of simultaneous connections from a single IP address, or perhaps limitations within your Windows operating system. Can you provide details on which version of Windows you are using? Additionally, it would be helpful to know if your Apache installation is standalone or part of XAMPP.
