[Web-SIG] empty action attribute with forms in Google Chrome

[Randy Syring]

Thomas,

Thanks for your info.  Looks like I need to change my SOP.

And you are right, I should find a different list for these questions.  
I am using a python web app, but these questions are generic enough to 
go somewhere else.  Thanks for the kind word and your advice.
