[Webware-discuss] Re: MVC help

Thanks for the help.  I tried this method and it does what I need it to do.  I 
am wondering though if there is a cleaner way to do this.

vmhs_hotbit was added to the request instance.  You could just as well add it 
to the transaction instance.  Is there a convention for passing objects or 
variables?  I would hate to clobber some attribute of request or transaction 
by accident.

Any suggestions?  Maybe I could create an object in my SitePage.py to hold 
variables, objects, etc. that I want to pass.
