any instruction to install and configure UI ?

gquintard commented 5 years ago

please check the README, your VCL is trying to access an html page that doesn't exist (I guess)

Is there anything other than "compilation failed" when you run the "varnishd -C" command? It's unlike varnish to just exit silently.

What varnish version are you running?

this is default.vcl

thatsk commented 5 years ago

@gquintard is there anyinformation you want?

gquintard commented 5 years ago

rtstatus.rtstatus() isn't a valid call, it appears that it's what's tripping the VCL compiler. Your code is wrong, but VCC should be more explicit. I'll open the relevant varnish bug.

@gquintard i just made changs to syntetic compilation error gone. but not able to see any output.
