reported web request "request exceeds the maximum length."
Cause of error: asp.net default maximum upload file size is 4M, run timeout is 90S.
solution:
1. Modify the web.config file can change this default value
<configuration>
<system.web>
<httpRuntime maxRequestLength="1048576" executionTimeout="3600" />
</system.web>
<configuration>
2. Another approach is to modify the .NET FrameWork:
(1) Modify C: machine.config file under /WINDOWS/Microsoft.NET/Framework/v1.1.4322/CONFIG directory.
(2) Find "<httpruntime" change in value of the ideal value maxRequestLength This line, like you want to 8M, would enter 8192.
In this way, any web project you can upload a maximum 8M files.
3. By the way IIS limits the upload file size modification method:
(1) First, go to the IIS service process off, that inetinfo.exe process off.
(2) found in the system directory: windows / system32 / inesrv / metabase.xml "file, find a text editor to open and look AspMaxRequestEntityAllowed =" 204800 "This one, this is the default size of the iis upload files by default 204800Byte, that is 200KB, change it to the size you want it.
