public static com.helger.commons.state.EChange setResponseCompressionEnabled(boolean bResponseCompressionEnabled)

Enable or disable the overall compression.

Parameters:

bResponseCompressionEnabled - true to enable it, false to disable it

Returns:

EChange

isResponseCompressionEnabled

public static boolean isResponseCompressionEnabled()

Returns:

true if overall compression is enabled, false if not

setResponseGzipEnabled

@Nonnull
public static com.helger.commons.state.EChange setResponseGzipEnabled(boolean bResponseGzipEnabled)

Enable or disable Gzip compression. This only has an effect if isResponseCompressionEnabled() is true

Parameters:

bResponseGzipEnabled - true to enable it, false to disable it

Returns:

EChange

isResponseGzipEnabled

public static boolean isResponseGzipEnabled()

Returns:

true if GZip compression is enabled, false if not

setResponseDeflateEnabled

Enable or disable Deflate compression. This only has an effect if isResponseCompressionEnabled() is true

Parameters:

bResponseDeflateEnabled - true to enable it, false to disable it

Returns:

EChange

isResponseDeflateEnabled

public static boolean isResponseDeflateEnabled()

Returns:

true if Deflate compression is enabled, false if not
