Status: Closed
Bug Type: IIS related
Operating System: Windows 2000
PHP Version: 4.2.1
New Comment:
The problem is caused in my case by using mail() in PHP.
In one request do I use mssql*, mail functions and than redirect
(header('location: ...')).
Without using mail() all works fine. But when I use mail() I get "CGI
Error" in 95% requests.
Pedro's cgi.rfc2616_headers = 1 tip did not work in my case.
'Forground Applications' does "solve" the problem.
Mail server is local (standard) MS SMTP Service.
My conf is W2k / IIS 5.0 / PHP 4.3.2 / MSSQL 2k.

To follow up I set cgi.rfc2616_headers = 1 as Pedro suggested and have
had no problems reported since. So I suggest trying this to anyone with
these problems.

I am trying Pedro's cgi.rfc2616_headers = 1 tip. We noticed this
problem a few times a day on an WinNT, IIS, PHP 4.3, MSSQL 2000 setup.
I could also reproduce this with the bounce.php suggested a while ago.
I was cosidering switching to Apache untill I read the post above.

This is not just an IIS bug.
I receive this bug on a production Win2K server that uses Apache 2.0.x
and PHP as a CGI. The PHP script in question does not use re-directs,
however it does add header information.
When I comment out the MS-SQL commands, the error disappears. With
MS-SQL commands uncommented, it serves up a storm of these errors.
I will try the RFC option mentioned above my comment! Again, this bug
appears to NOT be related to just IIS but rather the MS-SQL support.

I think I find the solution for this problem (at least on version
4.3.1)...
Just put this line "cgi.rfc2616_headers = 1" on php.ini.
Please, send us a message if it works. I had this problem during much
time and looking for solution, I saw that many others have it too.
PS.: sorry if there is some english error.

Parsnip, it's an IIS bug. Have you tried php4isapi.dll? It completely
fixes this problem. I can send you my breakiis.exe so you can prove to
your managers that IIS can't handle multiple simultaneous to any CGI.
The trick is to get away from CGI.
This is right off the Microsoft site:
"The Internet Server Application Programming Interface (ISAPI) model
was developed as a higher-performing alternative to the Common Gateway
Interface (CGI). ISAPI provides a number of advantages over CGI,
including low overhead, fast loading, and better scalability."
"The chief difference between the CGI and ISAPI programming models is
the way processing is handled. With CGI, the system creates a unique
process for every request. Each time an HTTP server receives a request,
it initiates a new process. Because the operating system must maintain
all these processes, CGI is resource-intensive. This inherent
limitation makes it difficult to develop responsive Internet
applications with CGI."
