I'm not sure if this can be handled with the standard ParsePath, but it
is fairly easy to write your own extractor that can handle more complex
scenarios. Here's an example:
object ParamsExtractor {
def unapply(pp:ParsePath): Option[(Account, OrgUnit)] = {
val result:Box[(Account, OrgUnit)] = if (pp.wholePath.startsWith(path)
&& pp.wholePath.length == (path.length + 2)) {
val res = Full((XX,YY))
debug("Decoded URL: %s=%s".format(pp,res))
res
}
else
None
result
}
}
used like this:
case RewriteRequest(ParamsExtractor(account,orgUnit) , _, _) =>
(RewriteResponse(path), Full(account, orgUnit))
