(Updated Jan. 3, 2013, 8:26 a.m.) Review request for shindig, Ryan Baxter, Dan Dumont, Stanton Sievers, and Rich Thompson. Description ------- The gadgets js servlet response can never be 304. Even if the If-Modified-Since header present in the request header and the gadgets js content has been cached in browser. Shindig provides required js processors and optional js processors. In current implementation, the IfModifiedSinceProcessor is doing the right thing to set a 304 response status code and stop the other optional js processors. But CompilationProcessor, which is a required js processor, will always run and always use a 200 to overwrite the 304 status code. Thus in the gadget js servlet layer, it won't return 304. The proposed fix is to add a check in the beginning of CompilationProcessor, if the status code is already set to 304, the closure compilor won't start. In the gadget js servlet, also add a check for 304 status code. This addresses bug SHINDIG-1890. https://issues.apache.org/jira/browse/SHINDIG-1890 Diffs ----- http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/js/DefaultJsProcessorRegistry.java 1406188 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/js/JsServingPipelineModule.java 1406188 http://svn.apache.org/repos/asf/shindig/trunk/java/gadgets/src/main/java/org/apache/shindig/gadgets/servlet/JsServlet.java 1406188 Diff: https://reviews.apache.org/r/8766/diff/ Testing ------- Thanks, Marshall Shi
