Append uniqueid to a http request at varnish
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*
Re: Append uniqueid to a http request at varnish [ In reply to ]
Hi Uday,

I feel like we've explored this last year:
https://varnish-cache.org/lists/pipermail/varnish-misc/2023-May/027238.html

I don't think the answer has changed much: vmod-uuid is your best bet here.

Please let me know if I'm missing some requirements.

Kind regards,

hello Guillaume,

I am trying to install vmod_uuid on my centOS 7 machine

Resource i used:
https://github.com/otto-de/libvmod-uuid/blob/5.x/INSTALL.rst

I am getting below errors while running *make *command

Re: Append uniqueid to a http request at varnish [ In reply to ]
Hi Uday,

I'm not sure what went wrong, but this Dockerfile works:
from centos:7

RUN \
set -ex; \
ulimit -n 10240; \
yum install -y make automake pkg-config libtool python-docutils
autoconf-archive uuid-devel epel-release python-docutils; \
curl -s
https://packagecloud.io/install/repositories/varnishcache/varnish5/script.rpm.sh
| bash; \
yum install -y varnish-devel; \
curl -O
https://raw.githubusercontent.com/varnish/toolbox/master/install-vmod/install-vmod;
\
chmod +x install-vmod ;\
./install-vmod
https://github.com/otto-de/libvmod-uuid/archive/refs/heads/5.x.tar.gz

Also, I know you have heard it before, but Varnish 5 is ancient, please
don't use it and upgrade to something more recent, either 7.5 or to the 6.0
LTS.

Let us know how it goes.
