How does SAIX operate?

Hi,


If I visit http://www.lagado.com/proxy-test I get a report about my connection as below:

This request appears to have come via a proxy.

The proxy host is rba-cache1-vif0.saix.net which has ip address 198.54.202.234

The proxy server has announced itself as 1.1 dn-cache1 (NetCache NetApp/5.6.2R1D2), 1.1 rba-cache1 (NetCache NetApp/6.0.3P2D6)

The proxy informs us that the client host ip address was 41.242.161.127, 198.54.202.146

Presumably this is because of the way that ISPs in this country connect through Telkom?
 
All SAIX HTTP traffic gets routed through transparent SAIX proxies. It has nothing to do with the ISPs.
The reason why this is done is to save on International bandwidth.

If 10000 South Africans want to visit www.google.com then the first user requests the page and the proxy caches it. The following 9999 requests get the cached page from the proxy instead of from overseas.
This all happens transparently in the background but can cause problems for some users in some cases.

Your PC (41.242.161.127) <====> Transparent Proxy (198.54.202.146) <=====> Internet
This is only for HTTP traffic (web sites) as far as I know - I don't think any other common protocols (such as FTP) are cached.

It's the same with me on IBurst. This is the reason why I can't use OpenDNS. :(

Proxy Test
This request appears to have come via a proxy.

The proxy host is wbs-196-2-124-252.wbs.co.za which has ip address 196.2.124.252

The proxy server has announced itself as 1.1 jnb-cache03 (NetCache NetApp/6.0.4)

The proxy informs us that the client host ip address was 196.2.108.100
 
Thanks for that.

I was looking at playing Wurm (www.wurmonline.com ) but couldn't get connected on my Windows XP laptop or my Suse 9.3 or Gentoo AMD64 boxen.

I figured it had to be something to do with the way we connect from South Africa.

I notice that I have a decent connection when I play Unreal Tournament, though, must use another protocol...
 
I got this from the Wurmonline Developers:

This could be the problem if they do not comply with the HTTP 1.1 specification and still cache the Wurm Packs even though I include the following
CacheControl header,
Code Cache-Control "max-age=0, s-maxage=0, no-cache, no-store, must-revalidate, proxy-revalidate, no-transform"
which should prevent proxies from caching. Unfortunately some proxies ignore this header and still cache the packs.
