URL forwarding for Web Dispatcher (one portal- 2 apps - need two external URLs)

[Former Member]

Our requirement is to have 2 systems configured in this webdisp. Which I have done and can access through web disp host using direct URL.

Our URL dataflow is like this

App hosts (portal and SRM) --> Webdisp DMZ (hostname saprouter) --> using load balancer for external world.

External addresses for portal and SRM.

Market.abc.com
Campl.abc.com (both this address for same portal but diff app)
swim.abc.com - for SRM SUS

Portal Sceneiro

Our ennterprise portal also has a add on called biller direct and ESS. To login to portal we give http://sapepqci.abc.com:51400/irj/portal and to log in to biller direct we give http://sapepqci.abc.com:51400/bd/public/frameset_top_html.jsp

We have installed webdispatcher in DMZ.(hostname saprouter) I can access like this

http://saprouter.abc.com/bd  the page will show like this http://sapepqci.abc.com:51400/bd/public/frameset_top_html.jsp

and  http://saprouter.abc.com the page turns like this http://sapepqci.abc.com:51400/irj/portal

We will be  using load balancer and external names are like this for ESS portal
Market.abc.com=http://saprouter.abc.com --> page is coming no problem.

camp.abc.com  =http://saprouter.abc.com//bd/public/frameset_top_html.jsp --> How to confgiure? As our load balancer is getting anything with  saprouter.abc.com/ = market.abc.com

Second question.

We have SRM SUS ABAP page and I have configured that too in webdisp
host saprouter.

so if execute http://saprouter.abc.com:8000/sap/bc/bsp/sap/srmsus/default.htm I am getting that page without any problem. But for external world this need to be configured as "swim.abc.com" Which parameter I am missing as when we give saprouter.abc.com:8000 it is bringing portal and not SRM application.

How to configure that big SRM url to point to swim.abc.com using same webdisp?

Attaching my current webdisp profile.

Hi Keder,

For You first question, answer will be -

Setup rules as below in Webdispatcher whitelist where we need to define url rules like Permit(P) or Deny(D).

In your case you did setup as below

  1) Market.abc.com=http://saprouter.abc.com

  2) camp.abc.com  =http://saprouter.abc.com/bd/public/frameset_top_html.jsp

If the user will enter the any one of the urls the first conditon will be passed the reason is both urls having  http://saprouter.abc.com  is the common and then it is executing for all users.

So to avoid this, please apply below logic;

Ans -

1) camp.abc.com  =http://saprouter.abc.com/bd/public/frameset_top_html.jsp

2) Market.abc.com=http://saprouter.abc.com  

camp.abc.com  =http://saprouter.abc.com/bd/public/frameset_top_html.jsp --> Set this url first in rule file; so that if the user will use this URL then it will execute first and takes them to right page.

Market.abc.com=http://saprouter.abc.com   --> if the user will use this URL it will compare with condtion (1) and it will fail there because that is having extra path; then It will move to next level to comapare .so set this condtion in the bottem.

Set this url first in rule file;  >>

Where? In the load balancer right?  I think I cannot set this rule in sapwebdisp profile.

Hi Kedar,

Check the example in the below mentioned link for creating rule.
