Start varnishd with: -p vsl_mask=+Hash

The default setting for vsl_mask is:
- -VCL_trace,-WorkThread,-Hash,-VfpAcct

Documentation here:
https://www.varnish-cache.org/docs/4.1/reference/varnishd.html#vsl-mask

Are those %00 expected at the end of the Hash?

...
- ReqURL /sites/all/themes/allegiant3/g4www-style/dist/styles/style.min.1.css
...
- VCL_call RECV
...
- VCL_call HASH
- Hash "/sites/all/themes/allegiant3/g4www-style/dist/styles/style.min.1.css%00"
- Hash "444%00"
- Hash “www…..com%00"

Hello Vlad,

Normally, varnish is configured using either the command line or using
varnishadm. You can have a look at "varnishadm param.show vsl_mask"

But we could probably have a pointer in the doc. Care to do it?

Hello Vlad,

You are looking for the VSL mask, see man varnishd.

yes, these are the null character. This makes sure that
"hash("123");hash("456");" returns a different result than
"hash("1");hash("23456");"

Maybe null characters are part of the hash when a string is passed to
hash_data, I haven't checked...

Yes, they are necessary delimiters to avoid fields flowing into each
other.

Otherwise hashing ("a" and "bc") would be the same as ("ab" and "c")

However, it can be argued that they don't need to be in varnishlog,
