Merge r440160 from trunk:

* Extract stickysession information correctly in the case that it is given
  as parameter like in the following example:

  www.someplace.com/somewhere/?jsessionid=gggfgdufdfoef.server&parameter=value

  So far we were only able to handle stickysession information encoded in the
  following form:

  www.someplace.com/somewhere/;jsessionid=gggfgdufdfoef.server?parameter=value
