Verify the F5 is not rewriting the header when it is loadbalancing

My requirement is to verify the F5 is not rewriting the header when it is load balancing.I need to make sure all the header information is not changed from the original header. The target server in this case needs to have the full url and source IP in the header to function. Please suggest. VS is configured on port 80.

 

VS : 210.xx.yy.89:80

 

10:xx.yy.1:80--Pool member

 

10:xx.yy.2:80--Pool member

 

Will irule fix the issue?

    Hi,

    you could do a tcpdump on the external and the internal interface, and compare the two, to verify if the headers are the same:

    external: 

    tcpdump -nni 'name of external interface' host 210.xx.yy.89 and port 80 -A

    internal: 

    tcpdump -nni 'name of internal interface' port 80 and host 10:xx.yy.1 or 10:xx.yy.2 -A

    Best regards,

    Morten
