Win8 iis8.0 under the uploadify-v3.1 to upload files more than 30 m, HTTP Error (404)

Solution:

1. Change Web. config

Add
<Httpruntime maxrequestlength = "1073741824" executiontimeout = "50000"/>

Add

<Security>
<Requestfiltering>
<Requestlimits maxallowedcontentlength = "1073741824" type = "codeph" text = "/codeph"/>
</Requestfiltering>
</Security>

2. Set IIS

Open the IIS manager and find the default web site. Stop the service first.

Double-click "request filtering" in IIS.

Click "Edit function Settings" on the right to open the "Edit request filter settings" dialog box.

The maximum capacity length allowed is "30000000" by default, 30 m, and is changed to 1073741824, that is, 1g.

Start IIS.
