[thelist] SSL Form problem

[Mark Howells]

Hi all

I'm running into problems with a secure form transaction in IE6 on 
Windows.  I have a pretty standard HTML form, with around 60 fields, 
including some for credit card details.  If I call the form up in a 
browser using http://, then submit to an https:// address, the form 
submits with no problems.  If, however, I request the form through 
https://, then post to https://, the server returns an HTTP 400 error 
(i.e., the client is submitting a totally empty form via POST).  There 
are no Javascripts or any special submission functions involved, just a 
plain HTML form.

Has anyone come across this problem before?  Do I need to call the form 
using https:// or is a standard http:// form OK?  (I know that I need 
the form submission needs to be handled over https://.)

Thanks for your advice
