HTTP 405: The HTTP verb used to access this page is not allowed

On an html page, one of our customers was getting this issue. Despite asking him to change the extension to .asp, he insisted to have html extension and still process the HTTP verbs, where it is POST method here.

Situation becomes like this a static page wants to be read a dynamic page and process the values obtaining from POST method. Solution is to make the .html read as .asp with asp dll, just like we do html parse as php in Linux boxes Here are the steps to do it on a Windows 2003 machine

1. Start –> Run –> inetmgr
2. Websites –> website/domain name in question
3. Right Click on the domain –> Properties –> Home Directory –> Configuration
4. In the tab Mappings –> Add an extension for .html and .htm , if it is missing (most cases it will be missing) and edit to add all verbs (POST, GET, HEAD are needed)
5. Fields to be added are as below,

Executable : C:\WINDOWS\system32\inetsrv\asp.dll
Extension : .html
Limit to : GET,HEAD,POST,TRACE

And Click Apply, OK All is well !!
