I suspect what I am trying to do here falls outside of Varnish's intended purpose but here is what I am trying to do...<br><br>Instead of using Varnish to cache content for a single site with several backends, I want to use it to allow me to serve existing sites on different domains. <br>
<br>For example I can run varnish on <a href="http://test.com">test.com</a> and serve content from <a href="http://example.com">example.com</a> using this configuration.<br><br>backend test {<br> .host = "<a href="http://example.com">example.com</a>";<br>
.port = "80";<br>}<br><br>sub vcl_recv {<br> set req.http.host = "<a href="http://example.com">example.com</a>";<br> set req.backend = test;<br> return(pass);<br>}<br><br>But what if I have 1000s of backends and I choose them based on the domain that user's hit varnish with. Is this something Varnish handles or is it only intended to work with a handful of backends?<br>
<br>Also, it would be really cool if I could do something like this.. <br>sub vcl_recv {<br>
set req.http.host = "<a href="http://example.com">example.com</a>";<br>
set req.backend.host = req.http.host; <br>
return(pass);<br>
}<br><br>I'm guessing backends are defined ahead of time for connection pooling but maybe not. <br><br>Anyway, this is long enough, tell me if I would be nuts to try to do this with Varnish and if so what would be better. I'm tempted to write my own proxy but that seems like such a waste. :-)<br>
