Hello,
We have a confirmed bug report :
- https://bz.apache.org/bugzilla/show_bug.cgi?id=62852
It appears that when using proxy for a request, the method
request.getRequestHeaders() called on the request returned
HttpContext#getAttribute(HttpCoreContext.HTTP_REQUEST) returns only part of
the headers.
While it returns them all if not using proxy.
The headers (context) gets changed on line 189 in
org.apache.http.impl.execchain.ProtcolExec.
final CloseableHttpResponse response =
this.requestExecutor.execute(route, request,
context, execAware);
try {
// Run response protocol interceptors
context.setAttribute(HttpCoreContext.HTTP_RESPONSE,
response); <-- Here
this.httpProcessor.process(response, context);
return response;
} catch (final RuntimeException ex) {
Will debug further.
Felix
See:
-
https://github.com/apache/jmeter/blob/trunk/src/protocol/http/org/apache/jmeter/protocol/http/sampler/HTTPHC4Impl.java#L580
I tried to reproduce behavior with HTTPClient only but couldn't , so it
seems issue is somewhere in our code possibly due to interceptors or
request executor.
