Webdispatcher to forward requests from internet to intranet?

Question

We need to direct requests from internet to our content server which is in the intranet (so that the content server images can be seen from the internet).
We have a WAS WebDispatcher in the DMZ. Can we use this WD to provide the connectivity?
For example:
Our content server intranet URL is:
http://contenterv.com:1090/path/image.jpg
Our WebDispatcher URL is:
http://webdisp.com/app_name
http://webdisp.com/app_name  should resolve to http://contenterv.com:1090/path/image.jpg
We tried WD http forwarding but it just forwards the request, does not resolve the name transparently. So the forwarding works but since http://contenterv.com:1090/path/image.jpg is not known in the internet, it fails.
Thanks

No, this wont work, becuase you need reverse-proxy function rather than URL redirection, because internet user wont be access the intranet server even you give them the URL.
I cannot get you the detailed confguration, but you can refer to web dispatcher cascade configuration.  play with the following parameters:
wdisp/server_info_location
wdisp/group_info_location
wdisp/url_map_location

it's not ture, web dispatcher can be used reverse proxy, of course you also can use other solution like Apache. However it's not recommened to use NAT, which might breach your network security.
