What's the issue?\r\n\r\nhttps://stackoverflow.com/questions/38339156/can-amp-errors-containing-the-string-do-not-worry-about-it-be-ignored/38346568\r\n\r\n## How do we reproduce the issue?\r\n\r\nIn Mobile Safari AMP pages that include `<iframe>`s appear to be making network requests to the follow path \"/amp_preconnect_polyfill_404_or_other_error_expected._Do_not_worry_about_it\". This can be observed by monitoring network traffic on the device. It will also show with great frequency in the network logs of servers delivering the `<iframe>`d experience.\r\n\r\nThis preconnect polyfill is not documented (except for a few Stack Overflow questions) and may come as a surprise to those hosting an `<iframe>`d experience on an AMP page. The \"_Do_not_worry_about_it\" portion of the path does not allay any suspicions and does not provide any additional information about the feature.\r\n\r\nThis feature should be documented in AMP with enough detail for developers to understand and anticipate this behavior. I would also suggest that the preconnect URL reference the documentation so the documentation is more discoverable when someone does observer the URL pattern.\r\n\r\n## What browsers are affected?\r\n\r\nObserved in Mobile Safari.\r\n\r\n## Which AMP version is affected?\r\n\r\n1506041909031\r\n"},"comment":{"url":"https://api.github.com/repos/ampproject/amphtml/issues/comments/370362190","html_url":"https://github.com/ampproject/amphtml/issues/11408#issuecomment-370362190","issue_url":"https://api.github.com/repos/ampproject/amphtml/issues/11408","id":370362190,"user":{"login":"htrex","id":1732938,"avatar_url":"https://avatars2.githubusercontent.com/u/1732938?v=4","gravatar_id":"","url":"https://api.github.com/users/htrex","html_url":"https://github.com/htrex","followers_url":"https://api.github.com/users/htrex/followers","following_url":"https://api.github.com/users/htrex/following{/other_user}","gists_url":"https://api.github.com/users/htrex/gists{/gist_id}","starred_url":"https://api.github.com/users/htrex/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/htrex/subscriptions","organizations_url":"https://api.github.com/users/htrex/orgs","repos_url":"https://api.github.com/users/htrex/repos","events_url":"https://api.github.com/users/htrex/events{/privacy}","received_events_url":"https://api.github.com/users/htrex/received_events","type":"User","site_admin":false},"created_at":"2018-03-05T09:39:10Z","updated_at":"2018-03-05T09:39:10Z","author_association":"NONE","body":"this creates a huge number of 404 on the webserver logs, is this really necessary?"}}
