How to test varnish vcl file

Unlike most other configuration systems varnish went with a compiled configuration so if there is a mistake all you get is :

 

Starting varnish HTTP accelerator: [FAILED]

To check what the problem is use the following :

varnishd -C -f default.vcl

varnishd -C -f default.vcl
Message from VCC-compiler:
Expected return action name.
(input Line 37 Pos 13)
return (hit_for_pass);
————############–
Running VCC-compiler failed, exit 1[root@MyHost1 varnish]# vim default.vcl
[root@MyHost1 varnish]# varnishd -C -f default.vcl
Message from VCC-compiler:
Invalid condition ‘&’ on numeric variable
only ‘==’, ‘!=’, ‘<‘, ‘>’, ‘<=’ and ‘>=’ are legal
(input Line 51 Pos 17)
if (obj.hits &gt; 0) {
—————-#——–

Rightly so the error shouts back at you with a # under it.

 

Very clear and to the point, the vcl I had was HTML’ed and replaced > with &gt;

 

That’s it..
