    13831383         people speak of retrieving some identifiable information via HTTP, they are generally referring to making a GET request.

    1385       <p id="rfc.section.4.3.1.p.2">If the target resource is a data-producing process, the produced data will be sent as the representation, not the source text

     1385      <p id="rfc.section.4.3.1.p.2">It is tempting to think of resource identifiers as remote filesystem pathnames, and of representations as being a copy of
     1386         the contents of such files. In fact, that is how many resources are implemented (see <a href="#attack.pathname" title="Attacks Based On File and Path Names">Section&nbsp;9.1</a> for related security considerations). However, there are no such limitations in practice. The HTTP interface for a resource
     1387         is just as likely to be implemented as a tree of content objects, a programmatic view on various database records, or a gateway
     1388         to other information systems. Even when the URI mapping mechanism is tied to a filesystem, an origin server might be configured
     1389         to execute the files with the request as input and send the output as the representation, rather then transfer the files directly.
     1390         Regardless, only the origin server needs to know how each of its resource identifiers correspond to an implementation, and
     1391         how each implementation manages to select and send a current representation of the target resource in a response to GET.
