I have a WCF REST service (.net 4) that uses PUT verb to create resources. (e.g., I send a PUT request to "http://xxx.com/Services/MyService/yyy") The service runs on my local web server but not on DASP. I get the an HTTP Error 405. Somehow, a WebDAV module seems to intersect the request (although I didn't configure anything...). Any idea how to enable PUT to my URLs? Here is the details error message: Server Error in Application "XXX.COM" "server_version"><p>Internet Information Services 7.5</p> <fieldset><legend>Error Summary</legend> <h2>HTTP Error 405.0 - Method Not Allowed</h2> <h3>The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.</h3> </fieldset> </div> <div class="content-container"> <fieldset><legend>Detailed Error Information</legend> <div id="details-left"> <table border="0" cellpadding="0" cellspacing="0"> <tr class="alt"><th>Module</th><td>WebDAVModule</td></tr> <tr><th>Notification</th><td>MapRequestHandler</td></tr> <tr class="alt"><th>Handler</th><td>WebDAV</td></tr> <tr><th>Error Code</th><td>0x00000000</td></tr>
