pecl.php.net download proxy script

Hello, a question about the pecl.php.net site that might be stopping server upgrades. The extension download URL endpoint is: https://pecl.php.net/get/operator This is a PHP proxy download script that do some checks and outputs non standard header for Apache webserver and mod_xsendfile to offer a direct file download as it was a static file. That way there is very little performance overhead and option that request goes through a PHP script. However, this mod_xsendfile isn't maintained anymore. And installation on today's Linux distros might not be so trivial anymore without patching the module's C code and compiling it manually. Overall, I'm not sure if using non standard Apache modules here is a good approach for production. Not to mention the portability of the app for the local testing environments. What would be the absolute right way to go here? A PHP only proxy downloader endpoint would be sufficient? Do you think performance would suffer greatly? -- Peter Kokot
