Single Web Dispatcher for Multiple SAP Systems

Having read a number of posts & S-Notes, I found that Web Dispatcher 7.2 is capable of routing between multiple SAP instances.

But despite having troubleshooted, I am unable to make it work. I have two separate installations ERP & Portal on the same host, but my web dispatcher only routes to one of them at the same time. Simultaneous access to these 2 systems is not possible either with URL or Port control procedure mentioned at url

Can anyone point an error in my below mentioned configuration of web dispatcher file.

I want requests on port 8853 of my web-dispatcher to be routed to system DEV &

the requests on port 8843 of my web-dispatcher to be routed to system DEP


rdisp/mshost = sapdeverp

ms/http_port = 8100

icm/server_port_0 = PROT=HTTP,PORT=8853

icm/server_port_1 = PROT=HTTP,PORT=8843

wdisp/system_0 = SID=DEV, MSHOST=sapdeverp, MSPORT=8100, SRCSRV=*:8853

wdisp/system_1 = SID=DEP, MSHOST=sapdeverp, MSPORT=8102, SRCSRV=*:8843


Can we mention multiple message servers instead of single message server "rdisp/mshost = sapdeverp

ms/http_port = 8100" ?

Any suggestions ?
