Hi Andre,
As Mark stated earlier - With a context.xml file named TestApp#web.xml you have
a defined a new
web application with a context path of "/TestApp/web" and a docBase of
"C:\web"
This holds true here. Any filter inside “TestApp” would not be able to catch
the requests going to "/TestApp/web" application.

Praddy

Then maybe try this :
Instead of :
<filter-mapping>
<filter-name>dir_filter</filter-name>
<url-pattern>/web/*</url-pattern>
</filter-mapping>
try :
<filter-mapping>
<filter-name>dir_filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Explanation : in <servlet-mapping> and <filter-mapping>, the <url-pattern> is
*relative to
the webapp context*. In your case, because of the way you have configured this,
the webapp
has a context of "/TestApp/web". Therefore, if you want the filter to apply to
everything
under "/TestApp/web", you have to map it to "/*".
So that, in URL-space, it will apply to "/TestApp/web/*".
The way you originally mapped it above, it would apply to "/TestApp/web/web/*",
which is
why it seemed not to be working. The filter was there, but never invoked,
because there
was never any request URL matching "/TestApp/web/web/*".
Clearer ?
Note that this is the same as what Mark was saying, only in many more words.
