[jcifs] Should I map all requests to the NTLM filter servlet??

[Allistair Crossley]

Hi Guys
 
I am working on an intranet and currently I have the NTLM servlet filter on all requests. I have a base action servlet that examines the session for our own user object. If it does not exist, it plucks the request.getRemoteUser kindly populated by the NTLM filter and then creates one of these user objects and uses the value to go and get various data from other internal systems.
 
The point is, I realised that there may be a performance hit running all requests through the filter. Does every request if mapped to the filter get routed for authentication with the domain controller? 
 
And if so, does anyone here think a good idea would be just to have a login servlet that the filter is mapped to so that I can create our user session object. All other requests would then not need to route through the filter.
 
Advice appreciated, ADC
