All,

Up to this point our application has used method="POST" for every form.  In 
general we're not too big on using GET due to the long messy URLs and people 
being able to save or share requests that may or may not work the same all the 
time for everyone.

For user experience reasons, we're looking at converting the "read only" forms 
to GET like they probably should have been in the first place.  When you go 
back to a POST, firefox does a nice job of just giving you a simple confirm 
message box.  Click yes and you're back at the results of the post.  But 
reasons I don't understand, IE8 went crazy and re-did this:  Send post, click 
back, get a white "page is expired" page (looks like an error), click refresh, 
get a message box, click retry, finally back at your results.  It's a lot of 
reading, mouse movement, and clicks just to go back and repost.  The average 
user gets lost and confused throughout this sequence and sees it as a bug on 
our end.
If I just change the method to GET it works fine, but the URL is extremely 
long.  It has the fp and sourcePage parameters in there which shows things like 
WEB-INF and other things I'd rather not have that visible.  Why aren't those 
sourcePage and fp parameters encrypted?

That aside, in order to switch this to get I'd like to do a couple things if I 
can:

1). Rewrite the query string from ?a=1234&b=2345=c=3456  to something like 
?q=6vhHABS59OP0ILkMJsL7yY5t==  . ... and the stripes side should still see the 
parameters as  "a & b & c", as it did before, no perceivable change from its 
perspective
2). Add a some tokens into the GET to keep track of when it was submitted and 
by whom so we can potentially block out old or unexpected requests.
#2 is not a big deal, we can do that fairly easily through a subclass of the 
form tag and an interceptor.  #1 however, I'm not really sure how to go about 
it.   I'm not 100% but I don't think the /clean/urls/feature can solve this as 
the form is kind of dynamic and has anywhere from 1-15 fields in the query.  It 
wouldn't translate to a restful URL.   Does stripes offer anything 'out of the 
box' that I can take advantage of?  I feel like I am missing something.

So far the best I can come up with is to put a servlet filter before the 
stripes filter that takes the "q" parameter, decodes it, and rewrites the 
getParameter() pieces to look into here instead.  Unfortunately this requires 
using HttpServletRequestWrapper, and due to no multiple inheritance, I have to 
literally copy a few pieces out of the servlet implementation we are currently* 
using.  So obviously that is a poor solution and I'm not going to do that.

Also, I'm not really sure how to encrypt the parameter on the client side.  I 
can hook into the form.submit() piece using jquery, but any encryption I put in 
there is client visible and can be broken.  Might I be able to hook into the 
form tag or something, or is just pointless base64 encoding the best I can do 
here?

Thanks for any input.
-John
