Meaning of non-SAP system and what it means relative to SAP Webdispatcher

[former_member237791]

Hi

We have a Web Dispatcher system setup which allow our SAP production environment to be accessed through the internet.

I have read in the documents that SAP Webdispatcher can be used to access non-SAP systems.

Does this mean we can access any other server e.g Lotus iNotes, using SAP Webdispatcher as a reverse proxy?

We currently are using Apache as reverse proxy to access our Lotus iNotes. Can we use Web dispatcher to access it?

Hi,

You cannot use SAP Webdispatcher as a reverse proxy but you can set up you non-SAP servers as external servers.  Take a look at the link i sent you.

Dear Michael

Thank you for your Answer.

We have tried what is suggested the SAP Help but it seems that we still have issues in trying to connect to outside servers. What we want to do is use the SAP Webdispatcher to Access our production SAP - which it is successfully doing using port 8443 and a redirect. We want to use port 8444 to direct us to another server(Lotus Inotes) in our case. Referenced below is the profile we are using. Can anyone assist us how to get connected to our non-SAP system.

Hi Haider,

Will you compare your profile with this SAP's example -

Hope this will help you in identifying what is right.
