I don't know if this is possible with web2py unless you write your own interface to WSGI.
I know in PHP or ASP when you print output it is displayed to the browser when it receives it, so on PHP websites that don't use template rendering, as soon as the print statement is executed it automatically goes out to the client browser, so over time you could send "print status" and the browser will display what it has received so far. You might want to take a look at web2py's download and streaming functionality, that might give you an idea where to start. -Thadeus On Thu, Sep 24, 2009 at 1:02 PM, Rob Scheibel <[email protected]> wrote: > > Thanks for the suggestions Thadeus.
