In brief:

IIS 7 + Apache Tomcat 7 + isapi_redirect.dll:

I have a deployed and working Tomcat-application available under http://localhost:8080/my_app.
I would like to see the same content under http://my_app.local (and NOT the default Tomcat-site [which you can see below]).
I set up isapi_redirect.dll, so right now my_app.local's content equals to localhost:8080's, but it's not enough, I would like to map localhost:8080/my_app under my_app.local. (I DO have my_app.local in hosts file, so I can already open my_app.local, BUT now it only shows the default Tomcat site (same as available under http://localhost:8080)).

Please read what I have already tried:

Longer explained:

I have IIS 7 (7.5.7600.16385) and Apache Tomcat/7.0.22 installed.

  1. I deployed an application (let's call it "my_app") in Tomcat, which now can be reached at http://localhost:8080/my_app, works fine. I added a new web site in IIS panel with the path of the Tomcat deployed my_app, which looks like this: "c:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\my_app"
  2. I binded the host name my_app.local.
  3. After that, I configured isapi_redirect.dll like this (or that).
  4. Now, when I open http://my_app.local, I can see the default Tomcat site (see below), which is the same as the content under http://localhost:8080/!! (That's the problem!!!)
  5. BUT under http://my_app.local I would like to see the same content as under http://localhost:8080/my_app.

How can I do that? Thank you very much in advance!!

I found this too: http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html

Case B: You need to hide path components for all requests going to the application. Here's the recipe for the case, where you want to hide the first path component /myapp. More complex manipulations are left as an exercise to the reader. First the solution for the case of Apache httpd:

  1. Use mod_rewrite to add /myapp to all requests before forwarding to the backend: [...]
  2. Use mod_headers to rewrite any HTTP redirects your application might return. [...]
  3. Use mod_headers again, to rewrite the paths contained in any cookies, your application might set. [...]

If you are using Microsoft IIS as a web server, the ISAPI plugin provides a way of doing the first step with a builtin feature. You define a mapping file for simple prefix changes like this:

# Add a context prefix to all requests ...
# ... or change some prefix ...

and then put the name of the file in the rewrite_rule_file entry of the registry or your isapi_redirect.properties file. In your uriworkermap.properties file, you still need to map the URLs as they are before rewriting! [...]
There is no support for Steps 2 (rewriting redirect responses) or 3 (rewriting cookie paths).

I was surprised that it writes "There is no support for Steps 2 (rewriting redirect responses) or 3 (rewriting cookie paths).", I don't know if it's still true, but then what? Am I stuck again?

Depending on your goal (easy to remember url?), maybe it's ok to just redirect my_app.local -> my_app.local:8080/my_app?

This would not hide the target site, however.

Setup a new IIS Site at my_app.local, and let it redirect to your :8080/my_app app.

No, unfortunately it's not an option to simply REDIRECT the address, I should serve the content of the site via the 80 port. For example, via IIS, I can serve ASP.NET or PHP pages too, through the 80th port, after installing the FastCGI PHP extension. –  Sk8erPeter May 22 '12 at 18:15
Effectively, what you want is a reverse proxy from iis to tomcat, right? See my other answer then. –  MichelZ May 22 '12 at 18:21

Can you try this: http://blogs.iis.net/carlosag/archive/2010/04/01/setting-up-a-reverse-proxy-using-iis-url-rewrite-and-arr.aspx

This seems to be what you need, URL Rewriting & Application Routing.
