Forum OpenACS Q&A: Re: OpenACS clustering setup and how it relates to xotcl-core.

Thanks for adding the nsstats feature for average time saved with caching. I will have to check it out

I found that the proc ad_canonical_server_p found in server-cluster-procs.tcl, did not work for us as we are using https (port 443). Included below is a diff of how I made it work. Feel fee to modify as needed. Note: We use nsssl_v4 in our config.tcl
