RE: [squid-users] is anyone listening to my queries summary o f events

mitesh
i did try to ftp a 1 GB file from an ftp server into the squid machine
the server was connected to the squid machine using ethernet
well i didnt get any errors
teh cpu was still abt 87% idle
i aborted th ftp session in between
77934800 bytes received in 456 secs (1.7e+02 Kbytes/sec)

i installed redhat 6.2 on an ordinary hp vectra machine
then i installed squid
i pointed my browser to this new squid
after each http request i get the same resource unavailable msg
the pages do load however.. i f any is thinking other wise
now according to squid Guru Henrick getting this msg is normal at debug
level 2
do others agree as well ???????

what is confusing me is that why dont i get this msg whenthe requests
are made by some other squid proxy or by polygraph for example

any more changes to be made to the kernel
Do excuse me if this msg seems very repetitive

hoping to hear from u guys
rgds
khizcode

so i am abt at my wits end
planning to install FreeBSd onthe compaq prolinea box to see if that
makes any difference
