Tomcat – Redirecting Tomcat requests to another host

redirecttomcat

How is it possible to redirect requests Tomcat 5.5 receives with certain URL match to another Tomcat instance on another host, like I could do on an Apache host with rewrite rules?

Example:
I'd like to redirect all requests on http://example.com:8080/xmpl to http://example.org:8080/xmpl (with full path and GET parameters), but leave http://example.com:8080/regular for Tomcat at example.com on port 8080.
Here example.com and example.org are completely different hosts.

In the end, we used a placeholder webapp with URL Rewrite Filter, http://tuckey.org/urlrewrite/ and the filter configuration from Erik Isaksson. This spared us from rebooting the server, which was quite important for the specific case.

Iis – Page not redirecting correctly

I think you're making this a little more complicated than it needs to be.

In the root of your Default Web Site just paste the following HTML code. When a user browses to http(s)://exchange.foo.com they will be redirected to the secure OWA page.

<html>
<head>
<title>Just a second...</title>
<meta http-equiv="refresh" content="0;url=https://exchange.foo.com/owa/" >
</head>
<body>
<h1>Just a second while you are redirected to foo.com's webmail...</h1>
</body>
</html>

Tomcat – Pretty URLs when using Tomcat behind an Apache proxy

If you're rewriting everything to a common location, you would typically do something like this:

ProxyPass        / http://localhost:8080/foo/
ProxyPassReverse / http://localhost:8080/foo/

If you need different rules for different paths, you would probably use the Proxy flag on a series of RewriteRules:

RewriteRule /bar/(.*) http://localhost:8080/foo/app/bar/$1 [P]
RewriteRule /api/qux/(.*) http://localhost:8080/foo/api/qux/$1 [P]
RewriteRule /quux/(.*) http://localhost:8080/foo/quux/$1 [P]
RewriteRule /(.*) http://localhost:8080/foo/app/$1 [P]

The this will send things to the appropriate place in Tomcat.

The only complication is if the application dynamically generates URLs with fully qualified paths. In this case, you need to either fix the application, or use something like mod_proxy_html to rewrite links in your HTML content.
