I have a issue that I can find a consistent documentation to resolv. The squid manual describe the %{Header} parameter of the external_acl_type in squid.conf. But no mater what header I put, it always return a '-' to my external helper. So, Does the squid have any chance to give me the %{Content-Type} value of the header? I'm trying hard to find a way to give to the external program this information, but I dind't find any hint on google. -- Valter Douglas Lisbôa Jr. Sócio-Diretor Trenix - IT Solutions "Nossas Idéias, suas Soluções!" www.trenix.com.br contato@xxxxxxxxxxxxx
