The WebSEAL servers can be configured to compress data
that is transferred over HTTP between the WebSEAL server and the client.
WebSEAL uses the gzip compression algorithm
that is described in RFC 1952. Gzip is supported
by all major browsers.
HTTP compression in WebSEAL can be configured based on the following
types.
MIME-type
browser type
protected object policies or POPs
Compression based on MIME-type
You can create an entry in the WebSEAL configuration file
for each MIME-type or group of MIME-types for which data compression
is needed.
Compression based on user agent type
WebSEAL returns compressed data to user agents that request
them. A user agent is a client that initiates a request. Use the WebSEAL
configuration file to explicitly enable or disable compression for
various browsers.
Compression policy in POPs
Attach a protected object policy or POP to an object so
that WebSEAL disables compression of that object.
Data compression limitation
The transfer of compressed data between WebSEAL and back-end
servers is not supported.
Configuring data compression policy
Edit the WebSEAL configuration file so that you can specify
data compression policy for communication between WebSEAL and client
browsers.
