Method Detail

isGZipSupported

boolean isGZipSupported()

Checks the Accept-Encoding request header for a "gzip" token. Ensures that the protocol is not "HTTP/1.0", which does not correctly support GZip encoding (in older Internet Explorer browsers).

Returns:

true if gzip is supported by client

isCompressable

boolean isCompressable(String contentType)

Deprecated. Deprecated in Tapestry 5.3. This method is to be removed at a later date. The service's configuration is no longer used. Instead, contribute to and use CompressionAnalyzer.

Checks to see if the indicated content type is compressable. Many formats are already compressed; pushing them through a GZip filter consumes cycles and makes them larger.

Contribute content type strings to the service's configuration to mark them as not compressable.

Parameters:

contentType - the mime type of the content, such as "text/html" or "image/jpeg".

Returns:

true if compression is worthwhile
