Hi @vivianegoe, thanks for your question.
For reverse proxy configuration with any version of FME Server we have the following guides available:
https://community.safe.com/s/article/use-a-reverse-proxy-with-fme-server
https://community.safe.com/s/article/using-iis-and-arr-as-a-reverse-proxy
There are some sections which are only for FME Server 2015 or earlier, but the rest essentially applies to all FME Server versions greater than 2015. I hope you'll understand that we do not have specific instructions on configuring IBM WebSEAL with FME Server. The complexity and uniqueness of customer configurations and our lack of access to some reverse proxy/web application servlets means we just cannot test and therefore provide direct support for these configurations.
That said, I think there are two essential concepts that should apply to all reverse proxy configurations: the reverse proxy needs to be configured to forward requests to FME Server, and FME Server services must be configured to use the hostname of the reverse proxy. From https://community.safe.com/s/article/use-a-reverse-proxy-with-fme-server):
* Regardless of the reverse proxy used, you will need to configure a redirect/rewrite so that all URLs matching the pattern 'fme.+' are forwarded to FME Server.
* FME Server's Web User Interface uses various service URLs when submitting requests to each services. These service URLs must be updated to use the host name of the reverse proxy.
The guide for IIS will probably be helpful for extrapolating the configuration you need to IBM WebSEAL as it shows examples of URL forwarding patterns for FME Server.
I hope this helps.
Best,
Nathan
