gzip -is:module

Generic zip controlled by a function with type-specific branches

Gzip compression with default parameters.

Use gzip to compress the body of the response.

Convert an OutputStream that consumes compressed ByteStrings into an OutputStream that consumes uncompressed ByteStrings in the gzip format

Twin map for monadic transformation

Twin map for queries

The gzip format uses a header with a checksum and some optional meta-data about the compressed file. It is intended primarily for compressing individual files but is also sometimes used for network protocols such as HTTP. The format is described in detail in RFC #1952 http://www.ietf.org/rfc/rfc1952.txt

This is not a format as such. It enabled zlib or gzip decoding with automatic header detection. This only makes sense for decompression.

Decide which files to compress based on MIME type The ByteString is the value of the "Content-Type" response header and will default to False if the header is missing. E.g. if you'd only want to compress json data, you might define your own function as follows:

myCheckMime mime = mime == "application/json"

Gzip behavior for files Only applies to ResponseFile (responseFile) responses. So any streamed data will be compressed based solely on the response headers having the right "Content-Type" and "Content-Length". (which are checked with gzipCheckMime and gzipSizeThreshold, respectively)

Skip compression when the size of the response body is below this amount of bytes (default: 860.) Setting this option to less than 150 will actually increase the size of outgoing data if its original size is less than 150 bytes. This will only skip compression if the response includes a "Content-Length" header AND the length is less than this threshold.

Convert an OutputStream that consumes compressed Builders into an OutputStream that consumes uncompressed Builders in the gzip format

Ignore the Accept-Encoding header in the Request and attempt to compress the body of the response with gzip. calls compressWithFilter using compress. see also: compressedResponseFilter

Takes the ETag response header into consideration when caching files in the given folder. If there's no ETag header, this setting is equivalent to GzipCacheFolder. N.B. Make sure the gzip middleware is applied before any Middleware that will set the ETag header.

Compress files, caching the compressed version in the given directory.
