For a few days, I have been breaking my head over this issue: My goal is to create a filter which detects Ajax calls (using jQuery for Ajax, which adds "X-Requested-With: XMLHttpRequest" to the request headers). If some jsp is requested by an Ajax call, I want to process the jsp's output with this filter (extract the body, correct some entities and stuff, but this is not really important to know for this issue, especially since I don't even get this far).
I have implemented the filter structure as outlined here: http://download.oracle.com/docs/cd/B32110_01/web.1013/b28959/filters.htm With one adaptation: in the Filter I check for the "X-Requested-With: XMLHttpRequest" header, and when it is there, I do the pre-post thing mentioned in the article. If it's not, it just continues the chain. I left the rest of the files untouched. However, it isn't working as it should be. I actually see the "PRE" and "POST" lines in the Ajax output, however, most of the time there is nothing between them. And when I print the response length, it's 0 most of the time. This is all working fine using our old development platform (based on Resin 3.0.14), but it isn't working on the new one (based on Tomcat 5.5.20). When I request the same url via a browser, all is working fine. Also, when I disable the filter, all is working fine (however, without my desired changes). So it has to be in the filter's code. An idea, anyone? I have attached the relevant java code for the filter to this message in one tar file: http://www.nabble.com/file/p19265999/AjaxPreparationFilter.tar AjaxPreparationFilter.tar -- View this message in context: http://www.nabble.com/Filter-cuts-response-in-Tomcat-5.5.20-tp19265999p19265999.html Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
