HI , As I checked there is no support for the multipart contents(multipart/mixed, multipart/related, multipart/alternate) in the WebKit. What shall be ideal way to extend this support. There are two approach in my mind. 1)parsing the content's other than HTML and Store as cached obkjects in Cache manager. But if Cache is disable it will be a problem. 2)Deriving new class HTMLMultipartDocument from HTMLDocument /Document. Is there any other way to do it. Thanks and Regards Sachin
