ID: 9852 Comment by: wharrison at pro dot ie Reported By: ron dot baldwin at sourceprose dot com Status: Closed Bug Type: IIS related Operating System: Windows 2000 PHP Version: 4.2.1 New Comment:
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. Previous Comments: ------------------------------------------------------------------------ [2003-05-22 13:21:17] phpbugs at spudland dot com 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. ------------------------------------------------------------------------ [2003-05-12 07:27:01] pedro at fundacaounimed dot com dot br 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. ------------------------------------------------------------------------ [2003-04-17 20:43:39] ottawasixtyseven at hotmail dot com 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." http://msdn.microsoft.com/library/default.asp?url=/library/en-us/iisref/htm/ISAPIExtensions.asp Ottawa ------------------------------------------------------------------------ [2003-04-10 11:58:54] parsnip11 at hotmail dot com I'm using windows 2000 advanced server, service pack 3, pentium 2.2 ghz, 512 ram. The Usleep function is working for me intermittently and sometimes solves the problem.... mostly it's effective if I do a javascript redirect as opposed to using the header command. All patches and performance changes mentioned here havent done a thing to change this bug. PHP PEOPLE ---> You have just GOT to open this bug up. I can only work with iis in my current enviornment and not being able to do redirects with PHP is just crippling my applications. Huffing that Microsoft's products are broken is not an acceptable solution. This exactly the kind of thing that make managers say "I told you it should have been done in asp... enough with your goofy php!". please fix this bug! ------------------------------------------------------------------------ [2003-04-08 04:14:49] jitse dot groen at grib dot nl Dear all, I'm probably not as experienced in PHP as all of you but I found a solution that *seems* to work fine for our sites. I base this on tests with doit.php by frankielam. I should also mention running iisreset once in a while decreased the number of CGI errors per day. It takes about 1-2 weeks for the bug to become noticable to us. It is present before that time but will not show that often. Changing performance to optimize for applications I really cannot consider. How can reducing the speed of our servers be a solution? A possible solution though: After increasing the paging file size (virtual memory) I cannot reproduce the bug however often I try. I'm not absolutely convinced that this will do the trick, but for now, it works. I would be anxious to hear your experiences with this solution.
