“405 method not allowed” in IIS7.5 for “PUT” method

Question

I use WebClient type to upload *.cab files to my server. On the server side, I registered a HTTP handler for *.cab file with the PUT method as below:

Answer 1

For me this error wouldn't go away and allow PUT methods, whatever i did.. uninstalled webdav, put configuration in web.config to remove webdav from handlers and modules, and set up PUT as an allowed verb on the request filters on iis.. and ensure iis handler mappings handling the request had PUT configured..

My problem was eventually due to bad installation of ASP.NET 4.5 Extensions. Removed everything related to asp.net from server roles and features. restarted. readded the roles and restarted. everything worked with above config.

--- The below will make PUT be accepted, but will send it to the wrong handler. --ignore the below

finally, adding PUT verb as allowed verb on TRACE handler mapping on iis worked.. since i had enabled failed error tracing, and this verb was not allowing the verb.

last time i had the same problem on another server's IIS, it was due to a missing '/' at the end of the URL since it was using a default handler without using the default document probably and now i realize that.. so check IIS handler mappings if nothing else helps.
