Hi, I tried to accomplish the idea, which originally comes from Tobi and was discussed few days later. The idea is, that you should be able to set driver using HTTP header for single request. So I implemented a simple Rack middleware, which is checking for X-Deltacloud-Driver header. But instead of modifying ENV variable I used Sinatra 'set' helper (which is fixed and working in Sinatra 1.1.0).
So testing of this patchset is simple: $ ./bin/deltacloudd -i mock $ restclient RestClient.get "http://localhost:3001/api";, :headers => [ "X-Deltacloud-Driver:ec2" ]} => "<api driver='ec2' version='0.0.1'>........ RestClient.get "http://localhost:3001/api";, :headers => [ "X-Deltacloud-Driver:gogrid" ]} => "<api driver='gogrid' version='0.0.1'>........ RestClient.get "http://localhost:3001/api"; => "<api driver='mock' version='0.0.1'>........ Let me know what do you think and feel free to modify/add something into this path. One issue which I have in my mind is if this settings stuff is 'thread' safe, eg. if two parallel requests will not change driver setting at once. -- Michal
