Varnish + GAE

[Roch Delsalle]

Hi,

I would like to know if it's possible to use a Varnish server in addition of GAE ?

- Is it authorised by Google ?

- Does it work ?

Regards,

Roch

In general it shouldnt really be needed, Google have pretty good front
end servers (and you can make them caching)

But some people do proxy - mainly so their site lives on a dedicated
IP address, and so work around countries etc than opt to block
appengine.
(and/or so can use HTTPS on a custom domain)

... so in short proxying does work - google dont object ( but I dont
that specifically varnish is used, but dont see why not)

You can use Varnish with App Engine, but you'll need to find a place to host Varnish.

It may or may not make sense depending on the additional, cross data center latency it introduces vs. cacheability. It's arguable whether this is worthwhile. On the one hand, with Varnish you get features such as the ability to flush a cache and server side includes for pages that are mostly static, but on the other hand, setting caching headers is really, really easy.

To serve China temporarily, I'm experimenting Varnish on AWS with backend server at appid.appspot.com. I get 302 response from Varnish and a link to http://www.google.com/ . Is it blocked by Google App Engine?
