first of all many thks for your reply :-) I made the settings and more proposed, here my conlusions ... When I remove originserver the connection breaks immediatelly with "page cannot be displayed" When I set originserver forceddomain and connection-auth, sometimes it works, sometines NOT .... when it fails the client also receives a "page cannot be displayed" so the normal working of the application prompts the user a first time for credentials, this seems to work, the user can use the application and when he wanna click on a specific button, it works and not depending on what ? Below you get the last lines of the squid logging but I wonder to not always see the PARENT 10.66.125.102 but also NONE/ ??????? 1259769370.111 20 10.67.229.216 TCP_MISS/304 466 GET http://services.group.intranet/rec/Images/status1.gif - NONE/- - 1259769370.303 14 10.67.229.216 TCP_MISS/401 3016 GET http://services.group.intranet/rec/images/open_detail.gif - FIRST_UP_PARENT/10.66.125.102 text/html 1259769370.355 6 10.67.229.216 TCP_MISS/401 3301 GET http://services.group.intranet/rec/images/open_detail.gif - NONE/- text/html 1259769370.373 17 10.67.229.216 TCP_MISS/304 466 GET http://services.group.intranet/rec/images/open_detail.gif - NONE/- - 1259769377.543 13 10.67.229.216 TCP_MISS/401 3016 POST http://services.group.intranet/rec/Forms/BasicSkeleton.aspx?Nav=RequestA bsence - NONE/- text/html 1259769377.589 10 10.67.229.216 TCP_MISS/401 3301 POST http://services.group.intranet/rec/Forms/BasicSkeleton.aspx?Nav=RequestA bsence - NONE/- text/html 1259769377.692 102 10.67.229.216 TCP_MISS/200 130429 POST http://services.group.intranet/rec/Forms/BasicSkeleton.aspx?Nav=RequestA bsence - NONE/- text/html 1259769381.417 18 10.67.229.216 TCP_MISS/401 541 POST http://services.group.intranet/rec/Forms/BasicSkeleton.aspx?Nav=RequestA bsence - FIRST_UP_PARENT/10.66.125.102 text/html the POST in the last line just above is the query giving problems at time to time below the current config client_persistent_connections on server_persistent_connections on acl protime url_regex -i ^http://services.group.intranet/rec acl protime_src src 10.67.229.216 cache_peer 10.66.125.102 parent 80 0 forceddomain=services.group.intranet originserver proxy-only no-query no-digest connection-auth=on login=PASS cache_peer_access 10.66.125.102 allow protime cache_peer_access 10.66.125.102 deny all always_direct deny protime never_direct allow protime we are very closed to get a full final working solution but seems to miss something else .... any idea ?? > >Amos > ----------------------------------------------------------------- ATTENTION: The information in this electronic mail message is private and confidential, and only intended for the addressee.
