Prakash D commented on HTTPCLIENT-2228:
---------------------------------------
Let me explain the scenario, We have two components,
The first component is sending Host header so that it will be used as a virtual
host.
As it is multithreaded environment, If multiple threads are sending Host
headers, to the same backend (second component) with different host header
values, Some how it is setting one thread's header value to another thread.
This causes exceptions in the backend component. This behavior we observed with
the load tests.
Sample log:
[2022/07/17-18:14:11,068]-[FINE ]- [172]-[com.xxxxx.xxxxx..] virtual-host
override set: {+}*tenant2*{+}.************
[2022/07/17-18:14:11,071]-[FINE ]-[172]-[org.apache.http.headers]->> Host:
{+}*tenant1*{+}.****************
The tenant1 is the Host header from different transaction.
