I've got a blockfilter, that blocks all access to anything but the only url
that's allowed and reroutes to an errorservlet.
I've also got a method filter that blocks invalid http methods, but when a
request to an invalid url is forwarded to an errorservlet, it's not
filtered through my httpmethodfilter.
I have no idea about your source code, but a filter, like a method, will
handle the returning thread from after the :
filterChain.doFilter(servletRequest, servletResponse);
<filter>
<filter-name>MethodFilter</filter-name>
<filter-class>dk.maerskdata.custm.communication.filters.HttpMethodFilter</filter-class>
</filter>
<filter>
<filter-name>BlockFilter</filter-name>
<filter-class>dk.maerskdata.custm.communication.filters.BlockFilter</filter-class>
<init-param>
<param-name>ALLOWED_URL_HANDLE</param-name>
<param-value>/soap/servlet/handlerservlet</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>BlockFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>MethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

I just learned about filters and managed to get one up and running in a few
minutes. Amazing!
I originally had it mapped as:
<filter>
<filter-name>webAuthFilter</filter-name>
<filter-class>edu.asu.vpia.example.WebAuthFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>webAuthFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
It's working a little _too_ well. I'm using Struts, and the filter seems
to
be getting hit repeatedly before I finally see the page appear. My guess
is
that each 'forward' gets filtered.
I tried to change it to:
<url-pattern>/*.do</url-pattern>
So that my initial "welcome" page won't get filtered, and so hopefully only
the initial /editContact.do hit will get filtered, and only once.
Unfortunately, this isn't working--
URL's like http://abc.def.ghi/dev/processContact.do aren't getting
filtered,
and neither are
ones with parameters in the URL:
http://abc.def.ghi/dev/editContact.do?contactKey=4100&action=edit
So I'm guessing I've done the url-pattern wrong, but all the examples I can
find just have /* to filter all requests. I thought I saw a reference to
an
example app that uses filters, but I don't see it in the examples that came
with 4.1.12.
Thanks for any hints...
