option wpad via DHCP

I have the following option in /etc/dhcpd.conf:
----
# automatic web proxy configuration
option wpad                  code 252 = text;
option wpad                  "http://sit.iitkgp/proxy.pac\n";
----

In the client lease record, I get the following entry:

  option unknown-252
68:74:74:70:3a:2f:2f:73:69:74:2e:69:69:74:6b:67:70:2f:70:72:6f:78:79:2e:70:61:63:a;

My question is: can firefox (and other browsers) handle this response
from the DHCP server.
