Configuring Multiple SSL URls on Web dispatcher

[muzavor]

Hi,

How would the Multiple HTTPS urls be handled in this case.

I am working on a scenario where all the HTTPS URL will be using the same port 44300.

The SSL termination would take place on the Web dispatcher. The connectivity between Web Dispatcher and backend would be HTTP.

Can you let me know if such a scenario is possible and if yes then how could it be accomplished.

The below URL are for the Users accessing the servers through Web Dispatcher

https://a.b.com:44300

https://b.b.com:44300

https://c.b.com:44300

https://d.b.com:44300

wdisp/system_0 = SID=CR1, MSHOST=c1.y.com, MSPORT=8100

wdisp/system_1 = SID=HM1, MSHOST=h1.y.com, MSPORT=8100

wdisp/system_0 = SID=CR2, MSHOST=c2.y.com, MSPORT=8100

wdisp/system_1 = SID=HM2, MSHOST=h2.y.com, MSPORT=8100

icm/HTTP/mod_0 = PREFIX=/,FILE=/sapmnt/WD1/profile/icm_filter.txt

####    icm_filter.txt  ####################

if %{HTTPS_HOST} regimatch "a.b.com"

     SetHeader x-sap-webdisp-target-sid CR1

if %{HTTPS_HOST} regimatch "b.b.com"

     SetHeader x-sap-webdisp-target-sid HM1

if %{HTTPS_HOST} regimatch "c.b.com"

     SetHeader x-sap-webdisp-target-sid CR2

if %{HTTPS_HOST} regimatch "d.b.com"

     SetHeader x-sap-webdisp-target-sid HM2

My queries are about the below

1) is the above config possible?

2) Is HTTPS_HOST a valid check, i know we can use HTTP_HOST in icm_filter rule file. Can HTTPS_HOST too be used?

3) If webdispatcher is configured for SSL termination , then do i need HTTPS_HOST in the ICM Filter or can i continue with the same HTTP entry that is existing for the HTTP urls

The result should be

https://a.b.com:44300 --> http://c1.y.com:8100

https://b.b.com:44300 --> http://h1.y.com:8100

https://c.b.com:44300 --> http://c2.y.com:8100

https://d.b.com:44300 --> http://h2.y.com:8100

Do let me know if anyone can help with the required info for the above configuration.

Thanks

Hello,

Yes, the scenario you are describing is possible.

Instead of using modification rules, why not use the SRCVHOST argument of the wdisp/system_X parameter? The Configuring the Web Dispatcher for Multiple Systems - Clarifications and Examples - Application Serv... WIKI page will help you with this.

Anyway, if you want to continue using the modification rules, you should use HTTP_HOST no matter the protocol used. HTTP_HOST is related to the HTTP header "host", not to the protocol and hostname used at the internet browser.

Cheers!

PS: made a small correction, the correct argument is "SRCVHOST" (there was a typo )
