Parameter passing at every step

[bharatraj viswamani]

Hi,

I have 10 HTTP request. At each step do i have to send parameters with this 
request(username, password and domain) ? Is there a better way to send 
username, password and domain only once.

Otherwise thro wireshark i see a different user passed from 2nd request 
downwards. 1st request takes the parameter i send with my 1st request

Thanks
Bharatraj
