RE: Servlet Filters
If that doesn't work, you could try using the HttpServletRequest.getRequestURI() method to spot requests for /test/* and forward these requests to the right servlet or JSP. /Manne -Original Message- From: Trond Nilsen [mailto:[EMAIL PROTECTED]] Sent: 28 February 2001 22:51 To: Orion-Interest Subject: RE: Servlet Filters > We want to use a servlet filter to intercept *all* requests that come into > the web server.

Presumably you have something like this in your web.xml WhereStuffGoesByDefault /* So for /test/* you'd have TestServlet /test/* The problem is working out which order they're considered. I imagine it's probably the order they're specified, so you'd want the test one listed first in your web.xml. I'm assuming that by intercepting all requests you want everything (except test/*) to go to a particular servlet. If you just mean intercept and feed back whatever resource they asked for, then all you need is the second code snippet in your web.xml Trond.

Simply create a servlet that sends appropriate redirects then use s to assign it to URL's. -Joe Walnes

We created a "SuperServlet" that is set up as a filter and handles all requests, handing off the requests to the appropriate code based on some parsing, etc. We didn't clone mod_rewrite, we just did the pattern matching that we specifically needed. -- Joel Shellman Chief Software Architect http://www.ants.com/90589781
