RE: External URL help

["LOCHART,DOUGLAS E" <do...@cablespeed.com>]

Thanks Nick.

I figured it out just a little while ago.  For some reason 
I had a mental blockage keeping me from making the leap 
here.  I do this same thing (rendering the URL) for a 
Direct Link in a menu component I wrote.  I guess I was 
hung up on the whole external thing.

Actually one thing I figured out by trial and error was 
how to set the page name.  I could not find an example on 
how to set the page name and the TIA book glosses over 
this.  I see now its the first parameter.

I do have one more question on this matter though ...

I will be rendering a link to send in an email.  When I 
tested the link rendering I got a link with a jsessionid 
in it.
here is what I got.

/MensanaTestPortal/app;jsessionid=36173DB59075B0E518234D75FFCB8EA4?service=external/ExternalTest&sp=SCody

I don't think that should be in there.  How can I avoid 
getting that in the URL?  This session will be dead by the 
time they click on the URL.

Thanks again for the help

Where I am getting stumped is that I need to give someone a URL like "www.signmeup.com/app?Salesman=John Doe" or something of that ilk.  This URL that I give needs to activate an External Page.  I guess what I need is to send an already rendered   external link.
