A posting on Lift 2.2-M1's stateless mode

[David Pollak]

Folks,

For those of you building high volume CMS systems around Lift... please read: https://liftweb.assembla.com/wiki/show/liftweb/Stateless_Requests

It describes how to mark pages in your site as "stateless".  Those pages will render normally, but will not allow any session state modifying operations.  They will "do the right thing" if there is an existing session (all the SessionVars will be available for reading), but they will prohibit the setting of SessionVars, accessing CometActors or using most of SHtml.

Thanks,

David

Excellent!

My 100% stateless webapp I'm working on (well, 100% of the state is stored in the URL :) works just great with     

LiftRules.statelessTest.append {

  case _ => true

}

in my Boot and my container set with sessions disabled.  And, as expected, if I use something that requires session state (such as SHtml.text) I get a clear error message.

Thanks,

g

Does that mean you're buying the first pint next time I'm in London? ;-)

Of course ;)  Maybe even stretch to the second too...

I'm not building stateless apps and we're not famous for beer, but if
you like good wine, the next time you'll be in Rome (Italy), you've
found who'll buy the first glass :)
