This module provides basic support for X-Sendfile and X-Accel-Redirect headers.

Usage

Either compile again for the target .net environment or use the supplied .net 4 dll
For more details on what the below settings mean and do, please consult Apache or NGinx documentation

Install the DLL

• Copy the assembly compiled to the /BIN directory located in the root of your application.
  • If this directory does not exist, create it.
• Configure the module and handler to be loaded in the application.
  • Open the IIS7 Administration tool
  • double-click on your server node in the left-hand tree view, then expand the “Sites” node, and click on the site or application to which you would like to add your module and handler.
    • Select the “Modules” feature icon, then click the “Add Managed Module…” action, and in the resulting dialog box type in the module name (arbitrary) and the fully-qualified module type “XSendfile.XSendfileHttpModule”.
    • Press OK to add the module.

Select one of the optional configurations below:

Config the base directory if using X-Sendfile (optional)

Common Settings

• XSendCache: [NoCache|Private|Public] (defaults to NoCache)
