server cacheing?

Anon

Hi, I have a problem that I've been working on for a number of days now. I recently had to re-install apache-ssl with php support. I am running debian woody. I am having problems with a calendar website that you have to log in to. When I log into the site nothing happens. I do not get logged in. I am having trouble fixing it because whenever I change something in the code the changes do not appear on the page. I can check the page source to confirm this. If I rename the page and then load it, the changes appear. Although if I then load that renamed page on a different computer after I have changed it back to look like the original it will still appear changed on the new computer. This led me to believe that the page wasn't being cached locally but on the server. Does anyone know how to stop this from happening? I've tried putting in headers to the files to disable cacheing but they don't appear when loaded. The line:
#CacheNegotiatedDocs in my httpd.conf file is commented out. All of the following lines about caching are also commented out in my httpd.conf file. If anyone has any ideas they would be greatly appreciated.

Thanks

It's possible your web browser is doing the caching, and not your server. Try putting:

in the <head></head> tags of one of your pages as a test, and see if it fixes it.

You can also add this at the beginning of your script :
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

Remember that the function header() must be called before you output something (echo, print, ...)
