Indeed.
I had a problem where i’d allow a user to edit some of her/his details on the web site. Displaying the user’s data worked just fine,
however posting the data would ( for some users) result in loss of their session data.
Took several hours to hunt the problem down ( didn’t occur on my end, so happy hunting
) Turned out i had the ’edit my data’
form post to mysite.com whereas the users suffering from ’the bug’ were entering using www.mysite.com.
Posting this just to save others the frustration when running into the same problem. Always post to the exact same url as the
one used by the visitor when he/she logged in.
I’m gonna stick an icepick into my eye for a while now...
