When trying to connect to a service from a local office via the local proxy (using https), then upstream to the main proxy array and from there to the service, response times are very slow (in the region of 45-60secs). However when we connect direct to the service by bypassing the proxy in the IE5 configuration, response times reduce to around 4-5secs. From the logs attached it would appear that there are multiple requests for authentication being sent for each object within the page request and that authentication is not persistent for each session or even page call. Any clues would be appreciated!!!!!!!
