[I] [Bug] clickhouse query failed when client enhance by skywalking-agent [skywalking]
Echo-C-Yi opened a new issue, #13700:
URL: https://github.com/apache/skywalking/issues/13700
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues.
### Apache SkyWalking Component
Java Agent (apache/skywalking-java)
### What happened
When use clickhouse-jdbc query clickhouse data with skywalking-java 9.4.0 by http 8123 port occur error clickhouse unknownException 1002
Clickhouse-server occur 400 bad request exception.
### What you expected to happen
Normal query.
### How to reproduce
Query clickhouse with skywalking-java agent by http .
### Anything else
The problem is because skywalking-java agent will set few header in http request.
But clickhouse may check those header hardly then throw 400 error.
I set the environment config : SW_EXCLUDE_PLUGINS=httpclient-4.x then this problem fixed.
So will you check and fix this bug?

Personally, I am rarely working on plugin codes due to my limited time. You are welcome to submit a pull request for this.

Yes，but i think it may consider whether target server will reject those header or not.
Right now, this situation has occur , would you fixed this conflict in http client plugin and clickhouse server?

This looks like a collaborative x-plugin code interaction. httpclient plugin needs to follow some flag in running time context, and decide whether to inject header or not.
