I have a site that runs uploading service, it's in php coded. I had it running on linux server and it works fine but i tried to move it to my windows server, then it cant accept any download bigger than 7, 8MB. It just shows the following error:

The specified CGI application misbehaved by not returning a complete set of HTTP headers.

It actually displays this message after it uploaded the whole thing, which turns out nothing has been uploaded. For smaller files, it works fine.

The server PHP is installed as CGI. Seeking anyone with high server experience to guide me to solve the problem.

seems like a server problem....i have seen this before

Hi all, I tried to reinstall php from cgi to isapi but now it's not getting up. If anyone willing to help, please message me. I want php to work and the site to get up urgently. Thanks.

Might want to check those real quick:
php.ini defaults:

post_max_size = 8M
upload_max_filesize = 2M

and obviously

max_execution_time = 30 ; Maximum execution time of each script, in seconds

uploading a 10 meg file may take a while..

ruiner has it right. Make sure to restart your web server after making the change.

Hey,

Yeah the upload size in php.ini is in indeed an issue.

But as you said you PHP pages are not comming up, you may want to try the php reinstallation once more.
During the installation, in IIS, the web server Extensions make sure to give the .exe path rather than the .dll. The exe will reside in the bin folder .
In the properties for the web domain, the extensions should again be included with .php extension path pointed to the .exe

Restart the IIS services and the php will work out.

Eh, he stated the script worked with smaller files. So, ignore the psot above this one.
