issue: When you recently deployed a Web project on IIS, you found that the browser always reported no errors for Woff, woff2 fonts. Causes the browser to load the font report 404 error, which consumes 100-200 milliseconds of load time.
cause: Because server IIS does not recognize the svg,woff/woff2 file types, simply add the MIME type on IIS.
Workaround
1. Open the server IIS Manager and locate the MIME type.
2. Add MIME type Add three:
file name extension MIME type
. svg Image/svg+xml
. Woff Application/x-font-woff
. WOFF2 Application/x-font-woff
Note: The MIME types that are filled out in the IIS7 version of this article in the WIN8 environment are not the same in IIS6, IIS7 MIME type management, but are added in the same way and parameters.
