[Laszlo-dev] [Laszlo-user] setting timeout to longer than 30 seconds

[Sarah Allen]

huh.  I always thought the 30 second limit was a Flash setting, not an 
OL setting.  Is there any underlying limit that we should be concerned 
about?  We're seeing legitimate requests from some users that take 
longer than 30 seconds on slow connections and I was thinking of just 
increasing this to two or three minutes.  Other than the delay in 
finding out your server is down, are there any other drawbacks to a long 
timeout?

Thanks,
Sarah
