By default, the upload limit for IIS7 is 200K. When the upload file is less than 30M, you can set it by the following methods:
Find the ASP settings in IIS7, and in the "Limit properties" of ASP, the last line of "Maximum request principal limit", modify the value to be what you want, such as 2G (2000000000, Unit B). When the upload file requires more than 30M, continue with the following modifications:
1. Stop IIS7
2. Find the "C:\Windows\System32\inetsrv\config\schema\IIS_schema.xml" file.
This file is read-only and cannot be modified with administrator privileges. To modify the permissions of a file first, then remove the read-only attribute.
1. Right-click File---Properties--security, select Target user, tap Advanced, modify file owner;
2. Click Edit after OK, you can modify the current user's permissions, add "Write" permission. At this point, the permission setting is OK.
3. Remove the read-only attribute of the file.
Open the file with Notepad, find "", and Change "30000000" to the value you want (such as 2000000000) to save.
Add a read-only property to the "C:\Windows\System32\inetsrv\config\schema\IIS_schema.xml" file.
Start IIS7. I upload 120M video files through.
However, win2008 can only upload files that are less than 2G
Second, The IIS7.0 method is modified as follows:
Open IIS Manager – Double-click ASP in IIS – Open the Configure ASP properties for the program – expand throttling Properties, modify the value of Maximum request entity principal limit, and the default value is 200000 (that is, less than 200KB);
Change it to the size you want to modify, such as: 52000000 (50MB).
Edit Complete Click "Apply" ok!
