Comment(by s.christiansen):

 The configuration really seems to be fine - the redirecting of mobile user
 agents works just great otherwise.

 It still is the only problem that a redirect is taking place from
 www.wetter.info to mobil.wetter.info once the user agent request header
 contains anything that smells of "connec". :-(

 We already checked all of our matching patterns for the user agents - the
 string "connec" cannot be found in the whole Varnish configuration
 whatsoever.

 We suspect that there might be a connection with the "Connection: close"
 response headers that are being used in this system; I have seen 'mixed
 up' HTTP headers here at some point already.

 So the assumption at this point is that there are User Agent request
 headers which, by error, actually contain the string "Connection: close"
 (or part of it). This then would end up somehow confusing the matching..
 the picture is not very clear yet.

 We'll check on that.
