Web Dispatcher HTTPS - Multiple backends

Hi experts,

we have one webdispatcher in DMZ which is forwarding to different backends, depending on the URL you are entering to access the WebDispatcher (routing-rules).

So, we have host A = webdispatcher and host B and C which is an alias to host A.

If you are entering www.b.com you get another backedn as www.c.com.

Now we want to setup https for the webdispatcher.

My question, is, how do I have to issue the certificate-req for the webdispatcher?
For host A or for B and C.

If for B and C, where can I import multiple certificates, for me it look like I can do it only once and like there is only one certificate possible...

    Hi,

    One instance will have only one server PSE. So you have to request the certificate for host A only.

    Hello,

    The Web Dispatcher acts like a "reverse proxy".

    The end user will reach the Web Dispatcher only.

    Thus, you would need certificates for the Web Dispatcher hostname(s) only, not for the backend systems.

    I have now imported the certificate for host A, with credentials for user of host A and did restart the webdispatcher.

    However, if I go to a url via www.b.com I just a get blank page/error.

    How can I analyze the error?

    In the log I don't see a problem...on 1st view...

    wdisp/ssl_encrypt = 2

    wdisp/system_0 = SID= , MSHOST= a.com, MSPORT=81 ,

    wdisp/system_1 = SID = , MSHOST= b.com MSPORT=81

    icm/server_port_0 = PROT=HTTP,PORT=80

    icm/server_port_3 = PROT=HTTPS,PORT=443

    Kind regards
