Interesting. Generally, the "Page has Expired" message appears when an HTML page is configured (via HTTP Header or meta tag) to not cache the page ("no-cache" ) and the page requires form data be posted to display. Since browsers do not repost data when pressing back and the browser is told it cannot load the page from cache, the message in question appears. A common way around this issue is to set the HTML form to use method="get" instead of method="post".
That is the reason why the message will usually appears and a common work around. It doesn't answer why it would behave differently in the two circumstances; however, I thought you might find the information useful.

Apologies if this is not really a CGI issue, but I am not sure where
the problem lies.
I seem to be experiencing a difference between using an url that
contains a name that is defined in my pc 'hosts' file and just using
the IP address. For me this table just represents a 'translation' and
I have no idea why the server or browser would treat it differently.
eg between as400/cgiprdp/pgm1.pgm and 999.999.99.9/cgiprdp/pgm1.pgm
This first program displays a list of items. I click on an item to
see the detail (link to another CGI program). After, using the brower
back button I return to the first list page. There is never a problem
with the first form of url (as400), but using the IP form I get 'Page
has Expired' message.
Thanks for any ideas
