I agree with both David and Graham, Favicon.ico confuses a lot of people and setting HIDDEN PARAMETERS to the form might be a good solution. Indeed global variables are not the way to go since it will go horribly wrong when multiple users are using it, and with a reload (depending on your apache config/multiple processes/maxrequests etc. globals are not set correctly if the post is handled by a different process than the process serving the get of the form) another small tip is to look at your apache access_log and error_log. I have never ever seen requests come in twice, and I do a lot of low level HTTP stuff in my work (like building webdav, caldav servers etc.) . Dump your code and the Apache config together with your access_log and error_log (clear them, and make one request and post) so we can see what is really going on.

Is there a standard way to post variable between the handler and the post functions? > > > On 4/03/2010 11:41 AM, Graham Dumpleton wrote: >> On 4 March 2010 11:27, Rob Fowler<legal at mianos.com> wrote: >> >>> Although that works fine and will call my post function, the apache server >>> calls the handler a second time so all the local variables are new. >>> >> You better explain that a bit better.
