Unfortunately, this doesn't work:

set $cachevalidval "60m";
if ($remote_addr = "1.2.3.4") {
set $cachevalidval "1m";
}
proxy_pass http://127.0.0.1:80;
proxy_cache gitweb;
proxy_cache_valid any $cachevalidval;

I get complaints that $cachevalidval is an invalid time value. I've
tried doing things like having $cachevalidval only have a number and
then using "$cachevalidval"m but nothing works so far...

Thanks,
Jeff
