Convert all form processing to POST

[tablatronix]

Get is not a secure method of submitting forms on an open ap specifically.

• convert all to post

❓ leave url forms as get? but what if inputs get added later etc, not sure how to handle, all post for now.

support GET optionally ( for script based url programming )
the library seems to not care, however we can deny by checking
server->method() == HTTP_GET

why not form submissions POST and whatever's not a form submision GET?
if you are using a browser and not the captive portal using the back button becomes a pain in the ass if you navigate between POSTs

the change shouldn't be big either, i guess just changing the form to POST and making sure it gets the params from the POST rather than string, not sure if that part is not transparent anyway

[tzapu]

like you ve actually done in your last commit :P
i'll but out, you are a machine :D

I tested and changed all to post, I think it better than to have to decide which page will have a form on it etc. we can adjust as needed, if it is a problem with browser history.

• test all devices with POST on all forms provide feedback on browser back and refresh capability.

So far browser history works as expected

why not replace form buttons with actual proper links ?

hmm I am now wondering if semantically these should be styled links with hrefs, and only actual forms be forms with inputs... #410
