URL - User Agent question

[Bruce Wilson]

At serveral web sites I'm being recognized as some kind of robot 
whenever I try to access source information of a page from Revolution 
with "get url" or "put url". I believe it's because revolution is not 
netscape or explorer or some other large browser. Where in a URL do I 
include the user agent information if I want revolution to emulate 
netscape or explorer. And what words do I include? Mozilla?, IE?

For example where in the following URL would I put the user agent 
information?

http://username:password@www.investors.com/login.asp?/member/checkup/checkUp.asp?t=mrk&sp=

Thanks in advance for anyones help
