specify timeouts in config file

Don't make the same request to uplinks if time since last request is less than X seconds.

+1 on this, Also, should be able to set the time to wait for the timeout in the config. Although the packages were cached, it still took about 4 minutes to install Mocha due to the timeouts

Big +1 on this. Was very confused by the maxage config option for uplinks that is present in the default config, but doesn't seem to actually do anything! :)

+1 this would be really useful for us. Since the start of May we've made 14100 requests to npmjs.org. Of those 13358 were 304 responses and 704 were 200. Would be nice to not have to waste time waiting for npmjs.org to 304 :)

I think it was implemented in #47 . You can set maxage argument in config now.
