Support for sniproxy #30
Description
I think it would be better to support https://github.com/dlundquist/sniproxy instead of haproxy, because sniproxy can do wildcards, which are needed for e.g. Amazon Instant Video now as it checks region for .*\.eu\.api\.amazonvideo.com.
Also the configuration for sniproxy is very straightforward.
The current rules for Amazon translated to sniproxy are as simple as:
table hosts {
atv-ps-eu\.amazon\.com$ *
atv-ext-eu\.amazon\.com$ *
atv-eu\.amazon\.com$ *
.*\.eu\.api\.amazonvideo.com$ *
}
