Owin.Compression

IIS compression is broken / removed by the Microsoft.Owin.Host.SystemWeb. In short, this middle ware is to replace & reimplement a GZip'ed / Deflate'd response back to the client.

Usage

To use compression on the built-in mime types:

    appBuilder.Use<ResponseCompressionMiddleware>() // To use compression on default mime types

To use compression on your preferred mime types:

    IEnumerable<string> mimeTypesToCompress = ..
    appBuilder.Use<ResponseCompressionMiddleware>(mimeTypesToCompress);

Any others will be ignored / returned as uncompressed

Default mime / types

Several default mimetypes that support gzip compression have been added:

• text/*
• message/*
• application/javascript
• application/json

TODO

• Use a configuration for mimetypes: either from web.config, or other configuration
• Disable compression if Server capacity is near limit ( ?? )
• Instrumentation ( how long does it actually take for a server to compress a stream? )
