hello list, I see this config directive in squid.conf,but can't understand for it. # TAG: url_rewrite_host_header # By default Squid rewrites any Host: header in redirected # requests. If you are running an accelerator this may # not be a wanted effect of a redirector. # # WARNING: Entries are cached on the result of the URL rewriting # process, so be careful if you have domain-virtual hosts. # #Default: # url_rewrite_host_header on please help explain it.thanks. --jen
