[squid-users] Strange entries in access.log

[Dr. Lars Hanke]

Hi,

in my access.log I find entries like:

1418752070.702      0 172.16.1.66 NONE/400 3636 
%C0%0E%C0%0F%C0%07%C0%09%C0 - NONE/- text/html
1418752082.987      0 172.16.1.66 NONE/400 3636 
%C0%0E%C0%0F%C0%07%C0%09%C0 - NONE/- text/html
1418752083.490      0 172.16.1.66 NONE/400 3636 
%C0%0E%C0%0F%C0%07%C0%09%C0 - NONE/- text/html
1418752083.526      0 172.16.1.66 NONE/400 3636 
%C0%0E%C0%0F%C0%07%C0%09%C0 - NONE/- text/html

I guess that these come from a mobile phone, which is transparently 
proxied (the IP belongs to the router). The mobile receives "The 
requested URL could not be retrieved" "Invalid URL", which is not 
surprising given the log. However, the phone works when connected to the 
net directly.

The device is a Samsung GT-B5330 running Android 4.0.4 using the 
standard browser. Squid is 3.1.6 as current in Debian 6 (Squeeze).

Is this something known?
