[users@httpd] WebDAV reverse proxy SLOW

Dear all,

I'm configuring a reverse proxy with configuration provided below, for 
Apache 2.4 for Windows (I'm trying to bypass Windows authentication 
dialogs this way). It works, but file browsing is very slow: listing 
three files in a folder takes several seconds, dir /b/s comes line after 
line, and doesn't improve. In contrast, same WebDAV resource connected 
directly or via NetDrive utility is quite responsive. I suspect Apache 
does not reuse connections or similar problems, but can't find more 
parameters to tune. Please advise.

Problems solved, under Windows 8 you need to listen to localhost IPv6 
address as well.
