how can I avoid a page expired error?

[NotGiven]

The user searches and see the results, then clicks for more detail in a
result. He then clicks the BACK button in the browser to see the results
again and....gets a page expired error.

How do you get around this?

I suppose the page expired thing is when iexplorer needs to resend post
data to the server? Not sure anymore, but you could try to open a
session, store the post data and do a header ("location:" );.

I presume you are using a script from somewhere else. Check the html
source to set if there are any meta tags related to expiring (it is
easy to figure that out). If so, remove them from the php code.

Don't use POST for submitting the search.

I found that using "session_start( )" on the page submitting the form, or
on the target using POST, then returning to the first page will give
this error. Instead, I was forced to use cookies instead of sessions.

neur0maniak, I would not think so. After all, session and
cookie-based.

Try it and see for yourself.

Using a session_start() adds headers to the page that prevents caching
on the user's side

If you're using sessions, this is caused by the default value of
session.cache_l imiter being 'no-cache' in your php.ini file. You'll
need to change it to a less-restrictive value, which may or may not be
a security issue. In your case (a search) I'd guess it's not, and a
value of 'private' would solve the problem. http://us4.php.net/session
has more detail on session.cache_l imiter settings.
