Add EPHY_EMBED_PERSIST_FROM_CACHE, and try harder to get a cache
2005-08-17 Christian Persch <chpe@cvs.gnome.org> * embed/ephy-embed-persist.h: * embed/mozilla/mozilla-embed-persist.cpp: Add EPHY_EMBED_PERSIST_FROM_CACHE, and try harder to get a cache descriptor for the source URL. * src/popup-commands.c: (save_property_url), (popup_cmd_set_image_as_background), (save_temp_source): Use EPHY_EMBED_PERSIST_FROM_CACHE to try to get the content from cache when saving background, images or links. Part of bug #168554.
