JWS && Servlets with Virtual Hosts

[Adam Weigert]

Does anybody know how to make servlets specific to a certain virtual host. So that instead of  www.companyA.com/MyServlet and www.companyB.com/MyServlet being accessible by both hosts i want www.comapnyA.com/MyServlet only to run on www.companyA.com and not on www.companyB.com .... if this is possible please tell me so... if not please tell me... so I don't waste countless hours trying...   Regards, Adam
