about vcl

Yuri, I think it is:

You must use the "set" keyword to assign a value to a variable, in vcl.

An user can not create a variable, the only variables available to use
are the ones that Varnish provide, like: req.http.host, obj.ttl...

You can only alter the variables under the structures of:

resp
beresp
req
bereq
obj

> Most of these are typed, and the

The majority of those variables are typed, they must receive values
which are compatible with their type, as in, for a variable which type
is "int" (an integer) you must use "set" to assign a value of an
"int", for example: 10; Trying to set it to a string will result in
failure.

These are my understandings of the above, if anyone have something to
add, or to fix, please do it.
