What happens if you serve content with a different length than the Content-Length header

In FF it returns an empty PDF. In IE it asks for permission to download a 265KB PDF, but then the downloaded PDF is empty. In Chrome it just raises an the error of ERR_CONTENT_LENGTH_MISMATCH.

We're using Apache with PHP in FastCGI Mode (PHP-FPM) and after we removed the Header('Content-Length') stuff in /includes/vb5/frontend/Controller.php it seems to work in Chrome now.. Code:

// sendAsJsonAndCloseConnection Line 295 //Header('Content-Length' ...)

... grep -R --include=*.php "Content-Length" ./

On the advanced custom fields it says that the problem could potentially be with the max_input_vars value in the php.ini file. I increased my value from 1000 to 3000 and that fixed the issue on one of my sites.

apache php fcgi SetOutputFilter DEFLATE

You can add zlib.output_compression = On to your php.ini configuration file. This will compress the output regardless of mod_deflate.

It's been a while since I posted this question - I ended up enabling zlib compression via PHP.ini so zlib compresses PHP output while mod_deflate compresses everything else.

I'm thinking the reason it wasn't working (mod_deflate wasn't compressing PHP output) has to do with PHP running as CGI and not an Apache DSO...
