Mixin module that provides the following:
Access to the CGI environment variables as methods. See
documentation to the CGI class for a list of these variables. The methods are exposed by removing the leading +HTTP_+ (if it exists) and downcasing the name. For example, +auth_type+ will return the environment variable +AUTH_TYPE+, and +accept+ will return the value for +HTTP_ACCEPT+.
Access to cookies, including the cookies attribute.
Access to parameters, including the params attribute, and overloading
# to perform parameter value lookup by key.
The initialize_query method, for initializing the above
mechanisms, handling multipart forms, and allowing the class to be used in "offline" mode.
