Responses

Pode has support for sending back compressed Responses, if enabled, and if a client sends an appropriate Accept-Encoding header.

The followings compression methods are supported:

• gzip
• deflate

When enabled, Pode will compress the response's bytes prior to sending the response; the Content-Encoding header will also be sent appropriately on the response.

Enable

By default response compression is disabled in Pode. To enable compression you can set the following value in your server's server.psd1 configuration file:

@{
    Web = @{
        Compression = @{
            Enable = $true
        }
    }
}

Once enabled, compression will be used if a valid Accept-Encoding header is sent in the request.

Headers

For your Pode server to compress the response, the client must send an Accept-Encoding header for with gzip or deflate:

Accept-Encoding: gzip
Accept-Encoding: deflate
Accept-Encoding: identity
Accept-Encoding: *

Or any valid combination:

Accept-Encoding: gzip,deflate

If multiple encodings are sent, then Pode will use the first supported value. There is also support for quality values as well, so you can weight encodings or fully disable non-compression (if no q-value is on an encoding it is assumed to be 1)

Accept-Encoding: gzip,deflate,identity;q=0

In a scenario where no encodings are supported, and identity (no-compression) is disabled, then Pode will respond with a 406.

If an encoding is used to compress the response, then Pode will set the Content-Encoding on the response.
