The problem is that Apache does not recognize the semicolon that
separates the session id from the rest of the URL as being anything
special, so rules based on file extension for example, won't match
properly.

I have the following rewrite rule in my apache config to fix this:


<IfModule mod_rewrite.c>
RewriteEngine on
# Force URLs with a jsessionid to go to Tomcat. Necessary because
# Apache doesn't recognise that the semi-colon is special.
RewriteRule ^(/.*;jsessionid=.*)$ $1 [T=jserv-servlet]
</IfModule>


If you access a servlet via the standard-http port 80 (either running tomcat on that port or accessing it through apache) the encodeURL and encodeRedirectURL methods don't work properly in Tomcat 3.1. This is fixed in Tomcat 3.2beta2.
