Re: Overcoming POSTDATA Warning

I'm hoping that someone here can help us out. We are in
the process of re-writing the underlying code for my
website (link to old version below). The site is (and
will continue to be) driven by PHP, javascript, and MySQL.
The problem I'd like to overcome is the browser's
navigation backwards through the tiers of screens and
menus. We have a "Back" link on the required pages, but
I would like to let the user navigate via the browser's
built in "Back" function, without getting the following
warning (from Netscape, in this case):

This doesn't have much to do with either Java or JavaScript (which are
both very different). But, I will be glad to give you advice.
This message occures if you have any <form> elements with the attribute
method="post"
It may be possible to replace these with method="get".
The caveat is that generally forms submitted with "get" are expected to
NEVER alter anything (databases, files, etc...), where forms submitted
with "post" are expected to modify something, or contain data that
shouldn't appear in the URL.
There is nothing you can do in JavaScript (and even less you could do
in Java) to stop this. Its simply changing your HTML to use "get", and
your PHP to look in the post data instead of get data.
In the future, if you do feel the need to cross-post to multiple
groups, try to find relevant groups (none of the ones you selected
were), and also set a Followup-to header to just one group.
Hope this helps,
Daniel.
