I don't know how this thing works, but there's a trick to combine multiple
headers into one. You can use the add-header action of the http-request
ruleset, and build a new header from the two other ones. Example :
http-request add-header x-foo %[hdr(header1)]%[hdr(header2)]
Then you can balance on hdr(x-foo). I don't know if that can help you here.
