How to set a Header field on POST a form?
html, http-post, httprequest, javascript, post
Solution
It cannot be done - AFAIK.
However you may use for example jquery (although you can do it with plain javascript) to serialize the form and send (using AJAX) while adding your custom header.
Look at the jquery `serialize` which changes an HTML FORM into `form-url-encoded` values ready for POST.
UPDATE
My suggestion is to include either
- a hidden form element
- a query string parameter
Problem
How can I set a custom field in POST header on submit a form?
