Hi Aldo,
You should be able to create a URL rewrite rule to peform this pass-
thru as
detailed at:
http://docs.openlinksw.com/virtuoso/rdfiridereferencing.html#urlrewriteruleconductor
Note Virtuoso also has a http_proxy function as detailed at:
http://docs.openlinksw.com/virtuoso/fn_http_proxy.html
Thanks, I managed to create one using the http_proxy function and a
one liner VSP.
However, my attempts at creating a URL Rewrite rule did not work if
the host/authority piece of the rewritten URL is different than the
original. Is this possible?
[Hugh] Note sure what you mean by host/authority piece, are you
creating the
rewrite rule via the Conductor or manually by hand using the
functions ? If
the latter can provide details of the calls being made ?
[Aldo] I mean the domain of the URL.
For example:
Original URL:
http://myvirtuoso.com/foo/cars
Target URL:
http://bar.com/baz?q=cars
Where the second domain is hosted in a separate, unrelated machine.
I am using conductor UI, but currently on my phone;)
[Hugh] Ok, you could try to making a proxy virtual directory as
detailed
at:
http://docs.openlinksw.com/virtuoso/webserver.html#virtproxy
where physical path is the destination (http://bar.com/baz) and
the logical
is /baz. Then make a url rewrite rule which works on the logical
path /foo
and in the rule /foo/(.*) compose an internal redirect to /baz?q=
$1, which
should result in:
1. Requests to /foo/cars will be redirected to /baz?q=cars
2. /baz will send requests to baz.com where it will get /baz?q=cars
I hope this works for you ...
Very clever hack ;)
It sure works for that usecase and I did learn a couple of things down
this road. But what I am trying to do is to proxy ANY URL, which I
don't know beforehand, including the domain.
So, my examples were too simple ;)
Here are some new ones.
Original URL:
http://myvirtuoso.com/bar.com/thispage
Target URL:
http://bar.com/thispage
Original URL:
http://myvirtuoso.com/goole.com/
Target URL:
http://google.com/
I already fixed it via coding. By opening an http client, etc ;)
Thanks!,
A
[Hugh] We do not have a click-only-solution when domain changes. Thus
behind the virtual directory, one would need to write the logic in a
small vsp page to parse the path and call http_proxy or http_client.

Hi,
I would like to use Virtuoso as a transparent, pass-thru HTTP proxy
that works like follows:
http://myvirtuosoinstance.com/httpproxy?url=http%3A%2F%2Ffoo.com
%2Fbar
and ends up calling
http://foo.com/bar
under the covers via Virtuoso HTTP Client, transferring unmodified
raw
data ( can be of any mime type ).
What's the simplest way to achieve this?
Can it be achieved with just a rule?
No need for authentication, etc. Just plain GETs for now.
Regards,
A
