partial URLPatternMatching in Tomcat 4.0 (Servlet 2.3 spec)?
I wonder if Servlet 2.3's Filter allow partial URLPatternMatching. Something
like:
<filter-mapping>
<filter-name>timerFilter</filter-name>
<url-pattern>/Controller?action=timer*</url-pattern>
</filter-mapping>
If it can, then we can use the Filtering mechanism as a controller to do
request dispatching. We can avoid having thousands if statements in the
Controller and we can easily modify the dispatching route without recompile.
If it can't, is it something worth enhancing? What needs to add to have that
capability? Thanks in advance.

Out of Memory.

Hi
After I run tomcat 3.2.1 under Win2000 or Unix for couple days, I will get
out of memory problem.
What can be wrong? And how to solve it? Thanks.

Would/Must the RewriteValve do that?

While what you propose might be quite nice, Tomcat needs to conform to the
servlet spec's rules for what a legal <url-pattern> can contain -- it's
the same for both filter mappings and servlet mappings -- and this pattern
is not legal.
One strategy would be to match for "/Controller/*" and let the filter look
at the query parameters to decide whether or not to do anything
special. Otherwise, it can just pass the request on unmolested.
