[xwiki-users] Redirect loop

I'm having a similar problem as documented by others: when not logged in, XWiki redirects to https://domain.com/xwikihttps://domain.com/xwiki/bin/..... That is, it's doubling the base of the URL. I've seen similar discussion at http://jira.xwiki.org/jira/browse/XWIKI-3330?page=com.atlassian.jira.plugin… ...but I don't have any xwiki.base parameter in xwiki.cfg. Also, along the lines of http://jira.xwiki.org/jira/browse/XWIKI-479?page=com.atlassian.jira.plugin.… ...I don't know what to set xwiki.virtual.redirect to (and I'm not using virtual wikis). I do have ProxyPass and ProxyReversePass going on my Apache server, but they seem to be working just fine once I'm logged in to XWiki. Any suggestions? Anyone? Thanks for the help....
