The std module provides a tolower function which is cleaner to use
in my honest opinion.<br>
Either way would work fine though. There really isn't a wrong way
to do it.<br>

Hi,<br>
<br>
The varnish-4 Hashing documentation states; "It is worth
pointing out that Varnish doesn't lowercase the hostname or the
URL before hashing it so in theory having "Varnish.org/" and
"varnish.org/" would result in different cache entries."<br>
<br>
I would like to lowercase both the host and url during my
normalization routines in vcl_recv. Stackoverflow has an example
using embedded C;<br>

Is this the recommended approach -- and will it work with the variable definition changes in varnish 4? (I'm worried </span></code><code><span class="pln">VRT_r_req_url</span></code>(sp) may break).
Also -- what is the variable holding the Host string? Is VRT_r_req_host(sp) valid in varnish-4?
Many thanks,
~ Brice
