Since it is not possible to use the servers IP address instead of its host name, and, in my case, the servers are not accessible through a host name in every case, I have to use the relative URL. The relative URL is generated using the WOContexts directActionURLForActionNamed method.

Try appending a random number parameter to the URL:
... ?wosid=[SID]&_r=[RANDOM NUMBER]...
