For example, if you run &quot;pub install&quot; against a local server where &quot;/packages/&lt;name&gt;.json&quot; or &quot;/api/packages/&lt;name&gt;&quot; return non-200 responses, the verbose logs indicate that pub makes two HTTP requests to that URL."},"comment":{"url":"https://api.github.com/repos/dart-lang/pub/issues/comments/109455764","html_url":"https://github.com/dart-lang/pub/issues/571#issuecomment-109455764","issue_url":"https://api.github.com/repos/dart-lang/pub/issues/571","id":109455764,"user":{"login":"DartBot","id":8958862,"avatar_url":"https://avatars.githubusercontent.com/u/8958862?v=3","gravatar_id":"","url":"https://api.github.com/users/DartBot","html_url":"https://github.com/DartBot","followers_url":"https://api.github.com/users/DartBot/followers","following_url":"https://api.github.com/users/DartBot/following{/other_user}","gists_url":"https://api.github.com/users/DartBot/gists{/gist_id}","starred_url":"https://api.github.com/users/DartBot/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/DartBot/subscriptions","organizations_url":"https://api.github.com/users/DartBot/orgs","repos_url":"https://api.github.com/users/DartBot/repos","events_url":"https://api.github.com/users/DartBot/events{/privacy}","received_events_url":"https://api.github.com/users/DartBot/received_events","type":"User","site_admin":false},"created_at":"2015-06-05T22:08:56Z","updated_at":"2015-06-05T22:08:56Z","body":"<a href=\"https://github.com/larsbak\"><img src=\"https://avatars.githubusercontent.com/u/5858078?v=3\" align=\"left\" width=\"48\" height=\"48\"hspace=\"10\"></img></a> **Comment by [larsbak](https://github.com/larsbak)**\n\n----\n\n*Removed this from the [M6](../milestones/M6) milestone.*\n*Added this to the [M7](../milestones/M7) milestone.*\n"}}
