Internet Direct (Indy) Version 9.0.1 Beta

property Pragma: string;
Pragma is used in an HTTP client request, and has the same meaning as the CacheControl property used in HTTP/1.1. Pragma is defined to provide backward compatibility with HTTP/1.0.
Pragma may also contain implementation-specific extension values which are defined in the HTTP protocol. Pragma directives must be passed by a proxy or gateway application, regardless of their significance to that application, since the directives might be applicable to all recipients along the request/response chain. It is not possible to specify Pragma for a specific client. Any Pragma directive not relevant to the client should be ignored.
