As the title says, we have our elog running behind an Apache proxy that is also providing authentication. We also have top groups enabled.  The first time a user views a top group page with a fresh browser cache, the index is delivered, but requests for elog.css and lock.png are returned with http 302 with location set to the elog root.  (I.e., if the server is proxied under server.example.com/logs,  the first request for server.example.com/logs/TopGroup1/elog.css returns a 302 with location set to server.example.com/logs// ). 

Any subsequent visits return the files fine. The attached screenshot shows the network requests in chrome. 

Is this a proxy configuration issue, something we've set wrong in elog, ??
