Re: [WEB400] Preventing doubleclicks

You're right.  I've been writing small cgi ap's on and off since the days
of I/Nets webserver, and i've always 'rolled-my-own' so to speak - no
CGIDEV or eRpg or any other api wrappers.

I've almost always written the cgi in such a way that it doesn't matter how
many times they click a link, no-harm-no-foul.  This time, I wasn't as
diligent as I should have been, and i'm paying for it.

Over the years, I've tried several different ways to insure thread safe
cgi, but was never really completely happy or satisfied with any of them.

that's why I posed the question to the group, maybe there was a 'best' way,
i hadn't thought of.

thanks,

Rick

Richard,

The JavaScript solution we discussed sounds adequate for your needs.
However, if you were talking about a widely used Internet application, I
think a server based solution would probably be needed too.  On the
Internet, you can't always count on JavaScript to solve that type of
problem.

My Relational-Web interface automatically solves this type of problem by
queuing requests for the user, rather than launching a 2nd instance of the
application to handle the 2nd "click".
