Peter, thanks for the information. Also, thanks for mentioning the forum
resource. I was unaware of the domain and will visit to see what it offers.

IBM's engineer, Nadir Amra, who is responsible for Net.data, has always
assured that there is no commitment to remove Net.data from OS/400 as they
have done for other platforms.
You should take comfort that the IBM web based administration of digital
certificates via *ADMIN server has always employed Net.data and still runs
their original Net.data macros, some of which are quite intriguing to
examine. I consider it like REXX, which I use all the time (because it can
script both CLP and SQL in the same code) and possibly a bit like CLP.
These things are used all over the place for years. They matter little to
IBM as flagship products so they care less if they cease upgrading or even
supporting them. I would expect they may reconsider such removal like they
did when they displeases CGIDEV2 users when they tried to do something that
was going to mess with the Easy400 website. They did drop support for the
Net.data forum but I revived that all by myself and still pay the annual
rego fee for the dtwdude.com domain, even though sod all people visit the
site anymore

Peter.

Yes, the unique key mechanism as a decent security catch a decade ago.
Nowadays, not so much. The javascript disable event I may have to look at.
Won't keep the user from refreshing the page but the biggest issue
definitely is the double click. Appreciate that little tip.

I'm vaguely aware of the practice of generating a unique query string
parameter in URLs as a security mechanism. It also as the effect of
ensuring that users never see cached pages.

Regarding the problem of double-clicking on submit buttons and hyperlinks,
some developers use JavaScript to disable the event after the first click,
then re-enable it in the response.

Nathan.
