Did the default HTTP expires header change in Tomcat?

[Jonathan Eric Miller <je...@uchicago.edu>]

In the applications that I'm developing, I used to be able to click on the
Web browser back button to return to a page that contained form data that
was generated by a HTTP post. I noticed that it now gives me an error
message like "Page has Expired" when I try to do it. It does this in both IE
and Netscape. It never used to do this. Did the behavior in Tomcat change?

If so, what do I need to do to return to the previous behavior? Set an HTTP
header like "expires" or something?

I noticed the following in the release notes in the fixed bugs section.
Could this have something to do with it?

6151  Manager servlet behaves bad in IE without an "Expires: -1" http header
