CompressionEncodingFilter

public CompressionEncodingFilter(CompressionConfig.CompressionModeI compressionMode,
 int compressionMinSize,
 String[] compressibleMimeTypes,
 String[] noCompressionUserAgents,
 String[] aliases)

Creates a new CompressionEncodingFilter based on the provided configuration details.

Parameters:

compressionMode - is compression on, off, or forced.

compressionMinSize - the minimum size, in bytes, the resource must be before being considered for compression.

compressibleMimeTypes - resource mime types that may be compressed. if null or zero-length, then there will be no type restriction.

noCompressionUserAgents - user agents for which compression will not be performed. If null or zero-length, the user agent will not be considered.

aliases - aliases for the compression name as defined in the accept-encoding header of the request.

Method Details

applyEncoding

public boolean applyEncoding(HttpHeader httpPacket)

Specified by:

applyEncoding in interface EncodingFilter

applyDecoding

public boolean applyDecoding(HttpHeader httpPacket)

Specified by:

applyDecoding in interface EncodingFilter

canCompressHttpResponse

protected static boolean canCompressHttpResponse(HttpResponsePacket response,
 CompressionConfig compressionConfig,
 String[] aliases)

Returns true if the HttpResponsePacket could be compressed, or false otherwise. The method checks if client supports compression and if the resource, that we are about to send matches CompressionConfig configuration.

canDecompressHttpRequest

protected static boolean canDecompressHttpRequest(HttpRequestPacket request,
 CompressionConfig config,
 String[] aliases)

Returns true if the HttpResponsePacket could be compressed, or false otherwise. The method checks if client supports compression and if the resource, that we are about to send matches CompressionConfig configuration.
