I have developed a asp.net page that uses the LEAD(v 14.5) activeX control to display images from a central server. Everything works great, but today I noticed that every image that is displayed using the lead control is cached by internet explorer in the temporary internet files folder on the local hard drive. This is a problem because i am serving sensitive documents that cannot be maintained on the local machine. What would be the best method to keep these images from being persisted to the local machine? Thanks! Using LeadTools 14.5 ^^ JAVD    Report

If you do this, the Main OCX will prevent the images from being written to the IE Cache. Adam Boulad LEADTOOLS Technical Support    Report

If you do this, the Main OCX will prevent the images from being written to the IE Cache. UPDATE: Setting this property did not work for me under IE 6.  Images were still being cached. I came up with another solution; on pages that i did not want images to be sent to IE's cache, I forced caching off for the whole page. This enforcement is done through the Response object and modifying the page headers if (!IsPostBack) {     Response.Buffer = false;     Response.ClearHeaders();     Response.Cache.SetCacheability(HttpCacheability.ServerAndNoCache);     Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);     Response.Cache.SetExpires(DateTime.Now);     Response.Cache.SetValidUntilExpires(false); } Using LeadTools 14.5 ^^ JAVD    Report
