Hello I am developing some application written in GWT on App Engine. I'm on optimalization stage, so i want to allow browsers to cache as much of static files as possible.
If I don't put any static files in appengine-web.xml directly, App Engine threat all files in "war" directory as static files (except WEB-INF directory) and when I deploy my application I have about 450 of them. I read (http://code.google.com/p/googleappengine/issues/detail? id=1662) that App Engine sets default cache expiration time to 10 minutes (which is too short). So, if I want to set different time I need to define all my static files in appengine-web.xml (because if I define even one static file, App Engine abandon his default behavior, and don't look automatically for other static files) and set my expiration time for them in "expiration" attribiute. And then we come to my problem. When I put all my static files in appengine-web.xml for example like this: <static-files> <include path="/**.cache.*" expiration="3000d"/> <include path="/**.png" expiration="30d"/> <include path="/**.gif" expiration="30d"/> <include path="/**.jpg" expiration="30d"/> <include path="/**.css" expiration="30d"/> <include path="/**.html" expiration="30d"/> </static-files> on deploy I have error: Unable to update app: Error posting to URL:xxx 400 Bad Request Error when loading application configuration: Invalid object: Found more than 100 URLMap entries in application configuration See the deployment console for more details As I understand App Engine maps every of my defined static files to URL's, and it exceeds some limits (http://code.google.com/p/googleappengine/issues/detail? id=1444), but why was that working when I didn't specify static files in appengine-web.xml? App Engine choosed even more static files then (all from "war" directory). GWT generates many static files for its own (many js files, that can be cached forever), and if you use runAsync code splitting, there are even more of them. It's essential in GWT to allow cache this files, because that's what GWT is! If they are downloaded every time when user requests page, it doesn't have sense (at least in performance meaning). I assume that App Engine and GWT combination has strong support from Google (Eclipse plugin for example makes developing with them so easy), so I think that there have to be some solution. Is there any workaround for it? I just want to set cache expiration time for my static files.
