httpReadReply: Unexpected reply body data from "GET http://www.facebook.com/home.php" on random #67

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Just visit facebook with your account or other peoples profile
2.If Unexpected shows up... facebook page blank and sometimes needs to 
reload 5 times.
3.tested under squid2.7 same issue

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
lusca r14302 freebsd7.2 i386

Please provide any additional information below.
by adding some debug codes @http.c
len is always 1138, chunk size is zero chuck flag is zero
facebook always reply Transfer-Encoding chunked

workaround ... @squid.conf
acl facebook req_header Host www.facebook.com
header_access Accept-Encoding deny facebook
this will tell the facebook.com that the client doesn't support encoding.
disadvantage ... size from 30KB will became 129KB

Maybe facebook having issues on their cluster? They have problems quite often 
this
days... also they have very strange DDoS protection system, that block requests 
with
too long headers (i had to cut off Via:  and X-Forwarded-For headers!)

Not only facebook but contents that has Transfer-Encoding: chunked header
and some with Content-Encoding: gzip header

client req http1.1 -> squid req http1.0 -> facebook
facebook rep http1.1 -> squid rep http1.0 -> client

server_http11 solve the problem

Hm, I don't have that particular problem here. I'd love to see the full request 
and reply headers there.

How long are your Via/XFF headers exactly? :)

Are you seeing it now? I've been told by facebook devs that they've found and 
fixed
bugs in their code.

Nice. I've removed the http11 and so far its fine.
