IIS7 large file Upload ASP. NET IIS Configuration

There is no problem uploading large files under IS6, but migrating to IIS7, the HTTP 404 error occurs when uploading large files.

IIS configuration upload Size, webconfig

<!--configuration allows upload size--
Minlocalrequestfreethreads= "4" apprequestqueuelimit= "executiontimeout=" 3600 "/>"

The reason is that the default setting under IIS7 limits the upload size. The size setting in Web. config is not valid at this time.

Specific steps:

1. Open IIS Manager and locate the default Web Site. Stop first.

2. In IIS, double-click Request filtering to open it.

3. Click Edit Feature Settings on the right to open the Edit Request Filter Settings dialog box.

The maximum allowed capacity length, the default is "30000000", 30M, modify it to the size you need.

4. Start IIS.
