=head1 NAME
Bugzilla::WebService::Server - Base server class for the WebService API
=head1 DESCRIPTION
Bugzilla::WebService::Server is the base class for the individual WebService API
servers such as XMLRPC, JSONRPC, and REST. You never actually create a
Bugzilla::WebService::Server directly, you only make subclasses of it.
=head1 FUNCTIONS
=over
=item C<bz_etag>
This function is used to store an ETag value that will be used when returning
the data by the different API server modules such as XMLRPC, or REST. The individual
webservice methods can also set the value earlier in the process if needed such as
before a unique update token is added. If a value is not set earlier, an etag will
automatically be created using the returned data except in some cases when an error
has occurred.
