Example of resumable upload by PUT method. It works with PowUpload ASP.NET control at server side that also supports PUT method.
Before using this sample make the following steps:
1. Grant NETWORK SERVICE user for WRITE NTFS permissions to file "FileProcessingScripts/ASP.NET/PowUpload/ResumableUpload.aspx". This is required because server considers the request sent by PUT method to "ResumableUpload.aspx" script to be an attempt to overwrite script file.
2. Open application properties at IIS, Under "Directory" tab and click "Configuration..." button. Select ".aspx" extensions in the list and click "Edit..." button. Add PUT verbs support i.e select "All verbs" or limited to "GET,HEAD,POST,DEBUG,PUT"
