mod_access_referer is an Apache module that understand the "Referer"
|
||
|
|
HTTP header, and grant or deny access based on the Web page that
|
||
|
|
refered the file.
|
||
|
|
|
||
|
|
The "Referer" HTTP header is sent by the browser to the server, and it
|
||
|
|
contains the URL of the resource from where the URL of the asked
|
||
|
|
resource was obtained. The document "Hypertext Transfer Protocol --
|
||
|
|
HTTP/1.1" RFC 2616 gives the following explanation:
|
||
|
|
"The Referer[sic] request-header field allows the client to
|
||
|
|
specify, for the server's benefit, the address (URI) of the
|
||
|
|
resource from which the Request-URI was obtained (the "referrer",
|
||
|
|
although the header field is misspelled.) The Referer
|
||
|
|
request-header allows a server to generate lists of back-links to
|
||
|
|
resources for interest, logging, optimized caching, etc. It also
|
||
|
|
allows obsolete or mistyped links to be traced for maintenance. The
|
||
|
|
Referer field MUST NOT be sent if the Request-URI was obtained from
|
||
|
|
a source that does not have its own URI, such as input from the
|
||
|
|
user keyboard."
