My question is that, the resource in the request line, /finger-pulse-oximeter-octivetech-300c-p-37.html?osCsid=ddd, is actually a web page, but why the referer, http://www.ddd.ddd.dd/ , is another page?
Try the following experiment : In your browser, call up the URL "www.google.com".Then, when that page is displayed, overwrite "www.google.com" and manually call up a URL on your server.
Then check your access log.You may find that the access to your own page is shown with the referrer "http://www.google.com";.
The point is, the server does not really know from which page, a page on your server is being called. It knows from which IP address it receives the request, but not from which page (and it does not have to be a page). So, in order to store the "referer" in the access log, it accepts whatever the browser (or other program) which accesses the current page, is specifying in the "Referer:" header that comes with the current request. If the browser (or other program) sends a request to your server, and adds a "Referer:" header containing "Planet Mars", then that is what your server will put in the access log.
Example :192.168.250.152 - - [02/Aug/2008:11:44:21 +0200] "GET / HTTP/1.1" 200 2355 "Planet Mars" "lwp-request/2.08"
The above line of access.log was obtained as follows :Along with perl, comes a very handy command-line program named "lwp-request", which allows one to compose a HTTP request to a HTTP server, specify exactly which headers are being sent, and look at the exact response sent by the server (headers and all).
The command I used was : lwp-request -Sed -m GET -H "Referer: Planet Mars" "http://localhost"; (the "-H" option allows to manually add a HTTP header to the request) André --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
