No, GWT doesn't actually cache them. It routes the request for your compiled resources through a proxy which is supposed to cache them (for up to 1 hour, I believe) > Historically my process has been to have the entire gadget inline as > type "html" and where necessary only include external resources after > using a call to _IG_GetCachedUrl so that they are proxies by google. > > So to clarify, my question is: When GWT spans it's code across > multiple files does it use _IG_GetCachedUrl to cache the request of > external javascript - or if not does it at least do something to > ensure that the javascript will not be requested (from my webserver) > every time a user loads the gadget. Turn on pretty mode when you compile, and then look at the generated .gadget.xml file (add -style PRETTY to the command line) and you'll see that this is exactly the strategy used in the compiled gadget. > just curious because on of the things I love about the whole gadget > space is that it has let me develop interesting projects in a way that > doesn't put much load on my puny server. There are things you need to watch out for. Make sure you load your .css files through a <script> take in your module definition (.gwt.xml). Also, images could be an issue, but you can translate the urls to images to go through the proxy with the same _IG_GetCachedUrl call manually, or you can use the new GadgetImage class (in the next public update, due out very shortly). > > thanks! > > > > -- Eric Z.
