| Summary: | 0001945: Comet style asynchronous requests | ||||
| Description: |
(rep by M Thompson) Using Resin, to provide event driven web applications using Comet (Reverse AJAX) style frameworks. We could use DWR <http://getahead.org/dwr/> [^] with Resin but this does not reuse the connection in the same way as it does with Jetty Continuations <http://docs.codehaus.org/display/JETTY/Continuations> [^] it is also possible with DWR and Lightstreamer <http://www.lightstreamer.com/> [^] . Other web containers such as Weblogic support asynchronous Servlets as an extension via AbstractAsyncServlet <http://e-docs.bea.com/wls/docs92/javadocs/weblogic/servlet/http/AbstractAsyncServlet.html> [^] . Given how Resin does not tie a thread to a connection it should be an relatively easy extension to allow the connection to be managed asynchronously to decouple the handling the request from the response. |

| Steps To Reproduce: | |||||
| Additional Information: |
This is a planned feature of the upcoming Servlet specification. Tomcat has builtin support for Comet, doc is here: http://tomcat.apache.org/tomcat-6.0-doc/aio.html [^] |
