Hmm. I'm very new to Zope, but hoping to come up to speed quickly. So please forgive my vast ignorance <grin>. I've installed SiteAccess, and am working on my SetAccessRule method. Evan suggests one can differentiate virthosts based on assigned IP by using the variable SERVER_ADDRESS. I tried that, and got an error message about that variable not existing. Now, I haven't gotten too far through the docs yet, where I'm sure this stuff is explained, but I wanted to get a couple things up and running quickly. So I figured, well, I'll just search the zope.org site for that variable to find out how to reference it correctly. No matches. Well, maybe that's not the right name...but, I should have gotten *one* match, on Evan's document where I read about it, right? So is something wrong with the search function on zope.org? Or am I not understanding what is indexed (in which case the search page could use some explanatory text)? (Also, although I found the section of the manual I was looking for, I haven't found the variable I need yet...) --RDM
