AGENDA
● Varnishd -C
● Inline c
● VCC file
● Demo
Fun fact:I’m a new OS X user.It took me 10 minutes of googlingto understand how to type this → “\”with this new keyboard.
Be nice to me!
VARNISHD -C
There is no VCL magic
Try it out with:varnishd -C -f your/vcl/file
INLINE C-CODE
Can do almost anything...
C{printf(”Arianna doesn’t like inline c!\n”);
}C
...but VMODs are better!
VCC FILE
Interface between VMOD andthe VCL runtime ("VRT")
And…the man page isgenerated from it!
