You could. In fact there's a trick you could use now which consists in using the "base" sample as a key for two maps. "base" contains the concatenation of the host name and the URI. For example : GET /foo/bar HTTP/1.1 Host: blah.example.org Then "base" will equal "blah.example.org/foo/bar". I think you see where I'm going now. You can simply build two maps, one for the uri part and one for the Host part, both indexed on the base, and retrieve each part from there. Hmmm thinking a bit more about it, I'm seeing an issue here. I don't see how I could replace part of a URI using sample fetch expressions :-( Well, if you don't have too many URIs to replace, you could at least apply them based on a condition (eg: if you only need to insert a few prefixes, you could simply condition a few reqirep rule on the output of the URI map). For example it could be more or less like this : reqirep ^GET\ /(.*) GET\ /foo/\1 if { base,map(prefix.map) foo } reqirep ^GET\ /(.*) GET\ /bar/\1 if { base,map(prefix.map) bar } reqirep ^GET\ /(.*) GET\ /com/\1 if { base,map(prefix.map) com } http-request set-header Host %[base,map(host.map)] There will be a few tricks that might be needed (basically, the "base" for setting the Host header will change due to the former rewrite), but before going into details, I'd need to know if you think this is something that could be acceptable.
