Hey,
I am looking at the logs and see that each and every request was served 
to the client..
it is even saying that the captcha object is imgae/png mime type.
What browser are you using?
and remove any firewall P2P or any other thing that can block the data 
from being transfered from the proxy to the client.
Also what "squid -v" output is?
it seems like you have some squid.conf settings which was applied in 2.7 
and are better removed in 3.X.
I would also change this line:
refresh_pattern -i \.(deb|rpm|exe|zip|tar|tgz|ram|rar|bin|ppt|doc|tiff)$ 
10080 90% 43200 override-expire ignore-no-cache ignore-no-store 
ignore-private
removing the "ignore-no-store" or splitting this rule in a way that the 
files such as deb and rpm tar tgz would be affected by some pretty wrong 
rules.
About the other extensions I would not say a word.
Regards,
Eliezer
