http://issues.apache.org/bugzilla/show_bug.cgi?id=37794 Summary: getParameter() fails on POST with transfer-encoding: chunked Product: Tomcat 5 Version: 5.5.12 Platform: PC OS/Version: Windows 2000 Status: NEW Severity: normal Priority: P2 Component: Servlet & JSP API AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Overview: When an HTTP/1.1 client (for example J2ME) POST with transfer-encoding: chunked to a servlet, the getParameter() family and getQueryString() methods fail to retrieve the correct result by returning nothing. In contrast, reading until end-of-file on the servlets input stream produces correct result. Steps to reproduce: Send a chunked POST request, with a=0 in the first chunk, sleep 1 s, then send &b=0 in the next, followed by a 0-chunk and trailer. On the receiving servlet, call getParameterNames() or getParameter(). Actual Results: null Expected results: a=0&b=1 Build: Tomcat 5.5.12 Additional Builds and Platforms: - getParameter() does fail on: Tomcat 4.1.18 Tomcat 4.1.24 Tomcat 5.5.12 - getParameter() doesn't fail on: Jetty 5.1.6 Additional Information: Please refer to the log below for Tomcat behaviour. It is from a simple test client and servlet written to demonstrate the bug.
