Proxy Component?
Is there any possibility to use Cocoon as proxy? I have some "old"
applications (written in PHP) that I want to use in combination with cocoon
(I want to use some actions)
for example:
<map:match pattern="old_application/**">
<map:act type="checkSession"/>
<map:proxy src="http://old_application_server/{1}"/>
</map>
<map:redirect-to uri="login.html"/>
</map:match>
Currently I solved the problem by using the HTML-generator but if I use it
the header information of the client will get lost.
If there is no available component - what would be the best way of
implementing it?
Regards,
Reinhard

Hmmm, not in the HTTP/1.1 sense.

Try using a Reader:
<map:match pattern="old_application/**">
<map:act type="checkSession"/>
<map:read src="http://old_application_server/{1}"/>
</map>
</map:match>
but I'm not sure it's fully action-safe since I don't know of anybody
using it for this.

Yes, it is availavle in C2.1-dev branch. I didn't send a patch for C2.0
cause it seemed to me that nobody is really interested in it. Just now I've
send the source of JSPReader adapted for C2.0 to cocoon-users mail list.
What do you mean by being a member of Cocoon2 project? JSPReader is just a
Cocoon component and if it is really needed to anybody else except me then
I'll spend a little time to improve it and provide some documentation.
You can find a sample of usage in C2.1-dev branch.

For purposes of migration, we're looking at starting from HTML JSPs, and your
JSPReader sounds like just the thing. Is it generally available? And,
frankly, why is it not a member of the Cocoon2 project? (The current
documentation on most of the Generators is sort of poor, as is.)

Does the reader use the client's header data (for example the User-Agent) or
get this data lost and are replaced with some other values? (I tested this
some month ago with the result that the values in the header were replaced.)
I think of a component that works like a resource reader but uses the
client's http-header data. What do you think?

You can create a reader for this purpose. I needed something like that to
get direct output from a JSP page (that is generating HTML, not XML) and
have implemented the JSPReader. Now you can use it like this:
<map:match pattern="old_application/**">
<map:act type="checkSession"/>
<map:read src="/jsp/page.jsp"/>
</map>
<map:redirect-to uri="login.html"/>
</map:match>
So, I hope you got the idea.
Btw, developers, there are ServletGenerator and JSPGenerator componenets
that implement almost the same thing: get output from a servlet then
generate XML from it. JSPGeneretor uses JSPEngine for that. Maybe it'll be
better to have something like ServletComponenet and use it either in
generators or readers that have to interact with other servlets?
