Hi ! Does anyone use Exchange-WebServices with squid ? We have it up and running with squid 3.1.19 under freebsd with the following config-options, but it takes very long to establish the first connection. When directly natting ews it's much faster. https_port xxx.xxx.xxx.xxx:443 accel cert=/usr/local/etc/squid/4f50b44b67bf9.crt key=/usr/local/etc/squid/4f50b44b67bf9.key defaultsite=g1.xxx.de cache_peer yyy.yyy.yyy.yyy parent 443 0 proxy-only no-query originserver login=PASS connection-auth=on ssl sslflags=DONT_VERIFY_PEER front-end-https=on name=OWA_HOST_pfs acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/owa.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/exchange.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/public.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/exchweb.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/ecp.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/OAB.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/Microsoft-Server-ActiveSync.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/rpc/rpcproxy.dll.*$ acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/rpcwithcert/rpcproxy.dll.*$ ignore_expect_100 on acl OWA_URI_pfs url_regex -i ^https:// g1. xxx.de/EWS.*$ cache_peer_access OWA_HOST_pfs allow OWA_URI_pfs cache_peer_access OWA_HOST_pfs deny allsrc never_direct allow OWA_URI_pfs http_access allow OWA_URI_pfs in the access.log we get the following errors 1331048055.562 6 207.46.14.63 TCP_MISS/401 312 POST https://g1.xxx.de/EWS/Exchange.asmx - FIRST_UP_PARENT/OWA_HOST_pfs - 1331048055.929 6 207.46.14.63 TCP_MISS/401 705 POST https://g1.xxx.de/EWS/Exchange.asmx - FIRST_UP_PARENT/OWA_HOST_pfs - 1331048056.186 138 207.46.14.63 TCP_MISS/200 1422 POST https://g1.xxx.de/EWS/Exchange.asmx - PINNED/OWA_HOST_pfs text/xml Does anyone have any experiences or ideas ?
