Thanks for the reply David.  I've tried using your stated command in 
place of the 'while' loop, but I'm still getting the same result - no 
content in browser.  Possibly a problem by not using the $SO named 
pipe?  I did take a look at the example page before I even contacted 
this mailing list, but I didn't see anything on there that was helpful.  
Any other thoughts?

Thanks,
Dave
