Does SharePoint hate "+?

Environment Description:

SharePoint 2007, IIS7, win 2008 server

Problem description:

In the SharePoint document library, when the uploaded attachment name contains a plus sign and the url is used for access in the browser, the system prompts that the file cannot be found, it does not work even if the + sign is converted to url encoding % 2B.

The error message of the accessed page is as follows: HTTP 404 Not Found.

 

Solution:

It is tested that access to such files is normal in SharePoint2007 and IIS6 environments.

Method 1: modify the configuration file applicationHost. config of IIS7

Method 2:

Using this command will make all sites take effect:
Appcmd set config "Default Web Site"/section: system. webServer/Security/requestFiltering-allowDoubleEscaping: True

Appcmd set config "Default Web Site"/section: system. webServer/Security/requestFiltering-allowDoubleEscaping: True/commit: appHos
After setting, you do not need to restart IIS.
