Different User-Agents send different req.url. To normalize them, see

http://www.varnish-cache.org/trac/wiki/VCLExampleNormalizingReqUrl

Note that technically, there's nothing wrong with using hostnames in 
req.url, apart from possibly storing the same object under different 
names. However, as you have found out, some regular expressions might 
not work as intended until you normalize req.url.
