Re: Prevent Browser From Going Back To Credit Card Page -- WEB400

X'15' is the wrong code. Although the Web server still converts it to the
right PC CCSID character it is doing so "manually". You should always use
X'25' for you linefeeds, and X'2525' for two line feeds.
When you send multiple HTTP headers, you end each one with a single X'25'
and the last one with two, X'2525'.
Normally HTML/CGI examples use the \n symbol to represent where the X'25'
goes. I sent this example earlier today, just replace the \n with X'25' in
your RPG IV code.

thank you.  I will try again.  the first time I tried it before any HTML, I
got
an error about not being able to display the page.  I must have had
something
else wrong.
do I still need the 2 newline entries after CONTENT-TYPE: TEXT/HTML or do I
put
these statements directly after and then do the 2 newline (x'15')
characters?

They are *NOT* HTML headers, they are HTTP headers. You need to send
them before you write any HTML out.

Do these go before the <HEAD> tag?

<SNIP>
Another thing you can do (you should actually do this anyway since you
don't want transactional data cached) is make sure that you're doing a
POST and write out the expire HTTP headers (these go after the
Content-Type header):

Cache-Control: no-cache
Pragma: no-cache
Expires: 0

When a person hits the back button, they'll get an error about expired
data.
