Apache HTTP Server 2.0.x and 2.2.x agents can encode special characters in cookies by URL encoding (6814694)

The version 2.2–04 Apache HTTP Server 2.0.x and Apache HTTP Server 2.2.x agents can use the new com.sun.am.policy.agents.config.encode_cookie_special_chars.enable property in AMAgent.properties to enable encoding for special characters in cookies. The default value for this property is false.

To enable the encoding, set the property to true and restart the Apache HTTP Server web container.
