Time-outs in LC Server?

[Rick Harrison]

Hi Alex,

The solution turned out to be easier with no time checks involved.

I noticed that one of my variables ends up being blank when the
server times out.  So when the user attempts to do something,
the destination webpage performs a check at the beginning of 
the code to see if the variable is blank.  If it’s blank, I have
alternate code appear that tells the user they have been logged
out due to inactivity, and offers a dismiss message button that
links back to the login page.  It works quite nicely, and
I don’t have to check for every transaction in every format file.

Enjoy your day!

Rick
