Append uniqueid to a http request at varnish

[Uday Kumar]

Hello all,

We follow below architecture in our production environment:
User request ---> Varnish ----> Tomcat Backend

We have a requirement of generating an unique id at varnish that can be
appended to a request url.
So that it can be propagated to the backend and also will be useful in
tracking errors efficiently

varnish version used: varnish-5.2.1

Example:
original request:
/search/test?q=bags&source=mobile

After appending unique id [This needs to be sent to backend and to be
stored in varnish logs]:
/search/test?q=bags&source=mobile&uniqueid=abc123

Please help us know if there is any way to do this at varnish

*Thanks & Regards,*
*Uday Kumar*
