Now replying to my own previous post, because I want to go to bed and so you would not have to wait for the conclusion :
My reasoning is that the browser does what it does, and what it does is right : if it sees the link <img src="image.gif"> in a page that it received when it requested
http://server/SEDO the it will request http://server/image.gif for the image. So far, ok for the browser, but that does not resolve your problem. To resolve your problem, the browser must known that when it requested http://server/SEDO what it really got was http://server/SEDO/index.jsp so that it can interpret the link <img src="image.gif"> as the request URL http://server/SEDO/image.gif The way to tell the browser that, would be that when it requests http://server/SEDOit receives a response from the server saying "no no, that's not there, but it's here instead" :
http://server/SEDO/index.jsp That is called a re-direct, or a 301/302 response.The browser, when it receives this, will (automatically and transparently) request again the resource, but this time as
http://server/SEDO/index.jsp and following that, it will correctly interpret <img src="image.gif"> as http://server/SEDO/image.gif (or http://server/SEDO_NEW/image.gif as the case may be) which URLs will be proxied to Tomcat and thus properly load-balanced. CQFD So now, the trick consists in having your server, upon request of http://server/SEDO to send back a re-direct to http://server/SEDO/index.jspand that is probably a matter for mod_rewrite, or maybe just a configuration directive in Apache.
(See the Redirect* directives)Note : in the URL to "redirect to", make sure that you specify it with a leading "http://server", because otherwise Apache may get smart and do an internal re-direct, which would not be known by your browser, and thus defeat the above logic.
Hope this helps, as they say.

I'm glad we managed to understand eachother :)Sorry, maybe I did not use the correct example before, but that is wrong.If you original request is http://172,18.0.1/SEDO and from there, your browser receives an html page (wherever it came from), and that html page contains a link <img href="image.gif">, then the browser will request http://172,18.0.1/SEDO/image.gifwait a minute.. maybe it won't. Because it would remove the "SEDO", forbeing the last path component, and replace it by "image.gif". Now I think I get it.The browser would have to know that it is not really getting "SEDO", but/SEDO/something. Hmmm. I guess that the only way to make this work (if you cannot change the <img> links in the pages), would be to force a re-direct to the real thing, when the browser requests "SEDO".That's what I tried before. But the thing is that I don't know where to redirect to, because: a. I don't know whether image.gif belongs to SEDO or SEDO-NEW b. I don't want to hardcode a Tomcat URL, because that server could be down. What is the resource that the browser really obtains when it requestsThe resource in the browser remains http://172.18.0.1/SEDO all the time.http://172,18.0.1/SEDO ? (this must be something on your Tomcats)While I see the following in my apache error logs: No such file or folder /htdocs/image.gif (More or less, I'm not behind that computer right now). I'm puzzled. I think it may have to do with ProxyPassReverse not being set properly. Wait. I repeat :What is the resource that the browser *really* obtains when it requestshttp://172.18.0.1/SEDO ? (this must be something on your Tomcats)that, which interests me.When the browser requests "http://172.18.0.1/SEDO", it first gets an html page. That page is probably defined as being your "Welcome document" forthat directory in Tomcat. What is that document ? Put another way, which equivalent URL could be used to get the same page from Tomcat ? (Maybe "index.jsp" or something ?) ---------------------------------------------------------------------The official User-To-User support forum of the Apache HTTP Server Project.See <URL:http://httpd.apache.org/userslist.html> for more info.
