I want to build an Internet Browser just like any other web browser or Internet Explorer except that each window should use a unique name for cache. Any ideas? Or any third party components?
I would recommend that you ditch TWebBrowser, and find out if TEmbeddedWB (alternative IE/shelldocview wrapper ) provides you with the ability to specify a different cache per instance. if not, then I recommend you ditch IE completely, and look for a webkit based browser control for Delphi, such as the Chromium-for-delphi wrappers.
