Re: [Jetty-support] How to forward SOME urls to another webserver ?

[Bhanu S. <bha...@gm...>]

First, about your comments :
A) Yes, I do mean forward the page requests to webserver B.
B) Well, I WAS toying with the idea of parsing all links in the document
returned and re-writing the urls (we may not have that many).....HOWEVER
there may be a way around if I can get 1) below to work ?

Now...about your questions:
1) Maybe I misunderstand Jetty proxy setup - but from the way *I* understan=
d
it, the proxy has a 'whiteHostsList' and 'blackHostsList' with which we can
control which sites can be visited.  However, what  I would like to do is
something like this : If we have 2 urls say http://localhost/abc.jsp and
http://localhost/def.jsp - I would like abc.jsp to be served up by my Jetty
webserver, but def.jsp request needs to be forwarded to def.PHP on webserve=
r
B.  What I am not sure about is, how to specify some sort of filtering wher=
e
ONLY def.jsp request will be forwarded to webserver B and others will be
displayed by Jetty (there may be several ways to do this).  I cannot
directly redirect def.jsp as that would be routed differently to B, and I
may not have access (firewall settings etc.).
2) Yes, the pages in B are written knowing this is how they will be used
- with relative URLs.
3) It's the user as a person who should not know about B.  That's the only
requirement.  I am trying to avoid replicating functionality on Jetty, by
directly using what's already in B.

Thanks in advance....any input on this is appreciated !

Cheers,
Bhanu.
