Hi,
Please keep mailing list.
Hmmm... are you going to realize the implicit HTTP proxy behavior as a
network side function? For example, when a client trying to connect to
HTTP server, the packets will be "implicitly" redirected to the HTTP
proxy, then some inspections or security checks will be applied, right?
If so, (sorry I don't know further) you need to some tricks or functions
before redirecting to the HTTP proxy, because there some differences on
HTTP headers between with and without HTTP proxy settings on the client
side.
e.g., Without HTTP proxy, a HTTP request should look like;
GET /news/index.html HTTP/1.1
but with HTTP proxy, the request should look like;
GET http://www.example.com/news/index.html HTTP/1.1
Just an idea, "transparent HTTP proxy" might be a hint for this
situation, but I don't know a lot.
e.g.,
client ---> transparent proxy ---> HTTP proxy ---> HTTP server

Hello, my mistake. I have an HTTP proxy (Squid ) and in my server, I run
a simple HTTP server(if your run python -m SimpleHTTPServer you get the
server). In the folder where I run my server, I have for example an
image. So, from hosts, I make get request ( I use wget ) to get the
image. So, I want to redirect this request throw my HTTP proxy. I think
the solution is to redirect the traffic from port 80 to port which the
proxy run. I made some changes in my topology, the proxy run inside the
switch. So, any ideas?

Hi,
First, please let me clarify your question. The "proxy" you
mentioned mean the HTTP proxy, right? If so, I this there are some
confusions in your situation. For instance, Squid HTTP proxy is an
application layer (layer 7) proxy for the HTTP(HTTPS) applications.
On the other hand, "ping" is an ICMP (layer 3) application to test
the IP reachablility and I guess these packets shouldn't go through
thw Squid proxy.
Pleases correct me if I have misunderstood.

I have a topology which includes these nodes,
Switch(s), Host1(h1), Host2(H2), Controller(c) where I run Ryu
controller and Proxy Server(ps) where I run Squid.
I want when I ping from h1 to h2 this "request" go throw the ps,
in ps Squid listen in port 3128. I find this
<https://github.com/zhewangjoe/of/blob/master/ryu-gpo/myPortForwarding.py>,
where make port forwarding. Because I am new to SDN, my question
is, is this a valid way to achieve what I want?
