Processing too long requests in mod_fcgid

Question

purpose

I want to show a helpful message to my client when the file they are trying to download is too large.

Problem

Right now mine is mod_fcgidthrowing 500 Internal Server Error when I try to send too large a request. I do not know how I can say this error:

• PHP error when display_errorsit was set to 0
• request uri for too long
• incorrect rewrite rules
• another bad configuration
• something completely different

If I tell the client “hey, you tried to load a file too large” in the 500 ISE handler, it will also run for all of the above, which makes no sense.

Things i tried

, , ErrorDocument 500 /generic-500.php. $_SERVER $_REQUEST .

:

• AJAX
• , 500 ISE

, .

500 ISE PHP , PHP POST?

Answer 3

What about set_file_buffer ($ f, $ b)? You can set the buffer size there - if you cannot do this work, I would use the output buffer methods to control it ...
