Hi All

I have written one client program to access SQUID.

My 'connect' call is returning 0.

I'm sending the following message to squid

GET http://www.yahoo.com HTTP/1.0
ACCEPT: */*

write is returning the proper number of bytes.

When I read the data from SQUID, I'm getting the 408 error.

If any one knows how to solve it please help me.

The client progrm that comes with SQUID s/w is also passing the same
request as I'm sending to SQUID.

I'm attaching my client program and the exact error message.

Thank you

Bye
