To simulate a chunked transfer-encoding in the response, I wrote a pair of
client/servlet classes.
- The client makes a GET request with a query string of TestSide=xxx.
- The servlet picks up the GET request in doGet(), simulate a buffer
of TestSize, and send buffer back to the client using chunked
Transfer-Encoding
by calling response.setHeader( "Transfer-Encoding", "chunked");
- The client reads the response and validate the size as well as the data
(both server and client agree on a same random buffer generation scheme)
When testing against tomcat 4.1.27 using Cayote connector, on the way back,
client (httpclient) detects the chunked encoding, but it complains with the
following
stacktrace
java.io.IOException: chunked stream ended unexpectedly

org.apache.commons.httpclient.ChunkedInputStream.getChunkSizeFromInputStream
(ChunkedInputStream.java:268)

.java:122)
at com.borland.ebu.qa.web.TestChunked.testGet(TestChunked.java:140)
By looking at the stack trace, I suspect that Cayotee connector does not
handle
teh chunking protocol correctly at server side.May be this is why this
simple unit test case
is not include in the test suite.
Any advice?
