New description:

 We have some trouble with the If-Match header. So far we understand If-
 Match or If-None-Match should be like this format

 {{{
 If-None-Match: "xyzzy"
 If-None-Match: W/"xyzzy"
 If-None-Match: "xyzzy", "r2d2xxxx", "c3piozzzz"
 If-None-Match: W/"xyzzy", W/"r2d2xxxx", W/"c3piozzzz"
 If-None-Match: *
 (Examples from http://www.freesoft.org/CIE/RFC/2068/187.htm)
 }}}

 In the varnishlog we see the format like

  BereqHeader    If-Match: W/0

 As you can see without quotation marks. Our expectation is like

  BereqHeader    If-Match: W/"0"

 It seems to be a bug in varnish.
