Is there any developer guidelines for using GET rather than POST in Moodle form submissions?
It appears the back end is agnostic as you can add the relevant terms to the end of a URL for a POST submission and the same results come back.
It appears at the moment POST may be slightly overused, which breaks browser navigation unnecessarily. Has this been done to avoid the internationalisation problems talked about at the end of this document?
The specific instance that prompted the question was Admin -> Edit User Accounts that uses a POST for sending the search query to narrow the list, which means if you do more than one search it breaks the back button.
I usually tell users that they can always use the back button unless they changed something, in which case they'll be stopped from making the same change twice. Hopefully that will remain good advice.
Sounds good. What do you need to set it up? My sourceforge id is "bawjaws". Anything else required?
