DNS Name to portal (short) URL

Question

Hi folks,
we are going to integrate some webapplications via url-iview in our portal (2004s). The applications have there own dns-name within our domain-dns-server.
After the integration, my plan is that the dns will be resolved into a portal (short)URL. In IIS i can take the hostheader for this, but how is it possible in the portal?
best regards
Frank

Hi,
ok I finally got it
You will encounter the following problem:
If you configure your alias ABC to resolve to the IP Address of your portal there is no application associated with it (/xxx) so you will always call the index.html (J2EE Startpage of your J2EE)
What you can do here is modify the index.html to redirect to a specific destination using meta http-equiv="refresh"
e.g.
meta http-equiv="refresh" content="0;url=/irj/portal/
Since it is just HTML you cannot disinguish and you will always be redirected to this destination when accessing the startpage or just http://portalhost
Now you have several ways to solve this:
1. I think that you can define Virtual Hosts in the HTTP Provider Service (Visual Admin / HTTP Provider Service) and Application Aliases (I've never done that but it should work). This means that you define a virtual host (e.g ABC) and map it to any application e.g /myAPP1 on your J2EE
see the following doc:
http://help.sap.com/saphelp_nw70/helpdata/EN/e5/ac55423948b330e10000000a155106/frameset.htm
2. You can change the Directory Index of your Engine (HTTP Provider / Properties TAB / Infer Names Property) and add something like index.jsp to the list
Default Value is:
{index.html,index.htm,default.html,default.htm}
Then you rename your index.html to something like startpage.html and put the index.jsp in the directory instead. In your JSP you will then be able to parse the Request (e.g. parse the Request URL, Headers etc. and send an appropriate redirect that fits your needs.) In all other cases you just send a redirect to startpage.html so you will still be able to see the Startpage if necessary
You have to put this jsp in the following path:
/usr/sap/<SID>/JC<InstanceNo>/j2ee/cluster/serverN/apps/sap.com/irj/servlet_jsp/irj/root
Note that if you are just typing
http://ABC and ABC will be resolved to your portal IP you will have to bind your portal to port 80 in order to make this work (I would not do that because you will get into trouble when upgrading or patching) or you will have to provide the port e.g. http://ABC:50000
If you do not want to provide the port than you will have to put a Proxy (e.g. IIS on the portal host that listens on port 80 and does whatever you like (e.g. parses HTTP Header and sends redirect or whatever)
Hope this helps
Cheers
