I have recently come across this problem and it has completely baffled me.

I have a site that is soon to go live and was testing it with Netscape. The pages submit information to themselves. In order for the content of the page to be updated there is a expiry meta tag.

The baffling thing is that on the development server there is no problem. On the live server when the information is submitted by 'post' method Netscape displays a error message saying that the content has expired.

The entire site works perfectly in IE. Whats starnge is that it works differently on the different servers. This is what leads me to think it could be a configuration thing. However I was sure that it was a purely clent side deal.

At the top of the pages that need it are these two lines:

<META http-equiv="Expires" content="0">
<META http-equiv="Pragma" content="no-cache">

The web server is Apache 1.3.11 on Redhat 6.1
Netscape Navigator 4.8

I would be sincerely grateful for any suggestions, help or directions to documents concerning this issue.

Thanks for any help in advance.
