iis6 and iis7 limit the upload file of request header size and do not support the FSO solution

Solutions:

1. IIS6 (2003 operating system)

The default limit of IIS6.0 in 2003 is 200K for uploading and 4M for downloading. Therefore, the above problems appear and are solved as follows:

1. Open the Internet information service (IIS) manager first
(local computer)-- properties -- allows direct editing of the configuration database (N)
1. Check "allow direct editing of configuration database (N)".

2. Then disable the iis admin service service in the service, using the command iisreset/stop

3. Find windows\system32\inesrv\ base.xml, open base.xml in the utility book, find ASPMaxRequestEntityAllowed, change it to the required value, default is 204800, that is 200K, change it to 51200000(50M)

4. Start IIS, command: iisreset/start

For security reasons, IIS 6 defaults to a maximum request of 200K(i.e., a maximum submission data limit of 200KByte, 204800Byte).

To find the < attribute name="maxAllowedContentLength" type="uint" defaultValue="30000000" / >
3000000 defaults to 30MB (not exactly). Plus 1 0 is 300MB. Modify as needed (1M=1024kB). Restart iis
Note: stop IIS service command iisreset/stop start IIS command iisreset/start restart IIS command iisreset.
