Hi,
I encounter An "invalid Response" on a particular site.
This is what I get from squid :
--------------------------
The requested URL could not be retrieved
While trying to process the request:

relaxed_header_parser value is at "warning".
I had a look at the headers, but couldn't find anything peculiar. But I'm not an
expert in this field.
Cache.log has said (I'm not 200% sure if it is related or not :

Two tcpdumps, one from the squid server, another one from another internet
access point, show strange characters just between the headers and the html
stanza. See the "5ea" , then the "1" , and the "0".
But this is through Wireshark and I'm not sure about the exactness.
