I am trying to create an AMP mobile web site with C# Web Form. I am receiving an error message when checking the AMP test page:
Use of prohibited or invalid HTML tags. The attribute 'action' may not appear in tag 'FORM [method = POST]'
This is the form tag on my website:
<form method="post" action="./amp.aspx" id="ctl01">
How can i solve this problem? How can i change action= to action-xhr= in the web form?
