APM Agent 10.7 breaks webapp inserting charachters in header

[Luca Razzi]

Hello community.
I have a web application running on Tomcat that has a security filter on the login page  that analyzes the header of the http request to prevent injectons and dangerous commands.
When APM java agent  (10.7 also no redef no retrans) is working ,it is rewriting the URL in the http header and the app stops working.

Is possible to prevent this?

Thanks Luca

​ Try setting the below properties to false in the agent profile

com.wily.introscope.agent.soapheaderinsertion.enabled=false

com.wily.introscope.agent.httpheaderinsertion.enabled=false

You will lose some cross-process correlation tracing functionality.
FYI there are corresponding properties for reading headers.

com.wily.introscope.agent.soapheaderread.enabled=true

com.wily.introscope.agent.httpheaderread.enabled=true

Really I found that is the agent triyng to follow the transactions because of the transaction definition in the CEM interface.
If the agent points to a MOM without CEM transaction definition in place, this behaviour ( writing url in HTTP header) is not in place.
 I put the settings you gave me @false but no way .
Only changing MOM succeded

The default behavior for 10.7+ agents is httpheader insertion and read. If you disable any of the parameters, it will break the cross-process correlation.
