Possible to combine calls in WCF? -

-

i have 2 methods need call in wcf application client.

authenticate(username, password) getuser(username)

is possible combine these calls avoid many calls being sent back/forth?

there few ways handle type of thing. first, can use wcf sessions initiate group of commands need maintain context between calls:

secondly, can take advantage of wcf's support ws-security standards avoid need pass credentials second call:
