-Some network label caveats
-* Cr-UI-Browser-Downloads:  Despite the name, this covers all issues related to
-    downloading a file except saving entire pages (Which is Cr-Blink-SavePage),
-    not just UI issues.  Most downloads bugs will have the word "download" or
-    "save as" in the description. Issues with the HTTP server for the Chrome
-    binaries are not downloads bugs.
-* Cr-UI-Browser-SafeBrowsing:  Bugs that have to do with the process by which a
-    URL or file is determined to be dangerous based on our databases, or the
-    resulting interstitials. Determination of danger based purely on
-    content-type or file extension belongs in Cr-UI-Browser-Downloads, not
-    SafeBrowsing.
-* Cr-Internals-Network-SSL:  This includes issues that should be also tagged as
-    Cr-Security-UX (certificate error pages or other security interstitials,
-    omnibox indicators that a page is secure), and more general SSL issues.  If
-    you see requests that die in the SSL negotiation phase, in particular, this
-    is often the correct label.
-* Cr-Internals-Network-DataProxy:  Flywheel / the Data Reduction Proxy.  Issues
-    require "Reduce Data Usage" be turned on.  Proxy url is
-    https://proxy.googlezip.net:443, with compress.googlezip.net:80 as a
-    fallback.  Currently Android and iOS only.
-* Cr-Internals-Network-Cache:  The cache is the layer that handles most range
-    request logic (Though range requests may also be issued by the PDF plugin,
-    XHRs, or other components).
-* Cr-Internals-Network-SPDY:  Covers HTTP2 as well.
-* Cr-Internals-Network-HTTP:  Typically not used.  Unclear what it covers, and
-    there's no specific HTTP owner.
-* Cr-Internals-Network-Logging:  Covers about:net-internals, about:net-export as
-    well as the what's sent to the NetLog.
-* Cr-Internals-Network-Connectivity:  Issues related to switching between
-    networks, ERR_NETWORK_CHANGED, Chrome thinking it's online when it's not /
-    navigator.onLine inaccuracies, etc.
-* Cr-Internals-Network-Filters:  Covers SDCH and gzip issues.
-    ERR_CONTENT_DECODING_FAILED indicates a problem at this layer, and bugs here
-    can also cause response body corruption.

-Common non-network label reference.  Bugs in these areas often receive the
-Cr-Internals-Network label, though they fall largely outside the purview of the
-network stack team:
-* Cr-Blink-Forms:  Issues submitting forms, forms having weird data, forms
-    sending the wrong method, etc.
-* Cr-Blink-Loader:  Cross origin issues are sometimes loader related.  Blink
-    also has an in-memory cache, and when it's used, requests don't appear in
-    about:net-internals.  Requests for the same URL are also often merged there
-    as well.  This does *not* cover issues with content/browser/loader/ files.
-* Cr-Blink-ServiceWorker
-* Cr-Blink-Storage-AppCache
-* Cr-Blink-WebSockets
-* Cr-Blink-XHR:  Generic issues with sync/async XHR requests - missing request
-    or response headers, multiple headers, etc.  These will often run into
-    issues in certain corner cases (Cross origin / CORS, proxy, whatever).
-    Attach all labels that seem appropriate.
-* Cr-Services-Sync:  Sharing data/tabs/history/passwords/etc between machines
-    not working.
-* Cr-Services-Chromoting
-* Cr-Platform-Extensions:  Issues extensions loading / not loading / hanging.
-* Cr-Platform-Extensions-API:  Issues with network related extension APIs should
-    have this label. chrome.webRequest is the big one, I believe, but there are
-    others.
-* Cr-Internals-Plugins-Pepper[-SDK]
-* Cr-UI-Browser-Omnibox:  Basically any issue with the omnibox.  URLs being
-    treated as search queries rather than navigations, dropdown results being
-    weird, not handling certain unicode characters, etc.  If the issue is new
-    TLDs not being recognized by the omnibox, that's due to Chrome's TLD list
-    being out of date, and not an omnibox issue.  Such TLD issues should be
-    duped against http://crbug.com/37436.
-* Cr-Internals-Media-Network:  Issues related to media.  These often run into
-    the 6 requests per hostname issue, and also have fun interactions with the
-    cache, particularly in the range request case.
-* Cr-Internals-Plugins-PDF:  Issues loading pdf files.  These are often related
-    to range requests, which also have some logic at the Internals-Network-Cache
-    layer.
-* Cr-UI-Browser-Navigation
-* Cr-UI-Browser-History:  Issues which only appear with forward/back navigation.
-* Cr-OS-Systems-Network / Cr-OS-Systems-Mobile / Cr-OS-Systems-Bluetooth:  These
-    should be used for issues with ChromeOS's platform network code, and not
-    net/ issues on ChromeOS.
-* Cr-Blink-SecurityFeature:  CORS / Cross origin issues.  Main frame
-    cross-origin navigation issues are often actually Cr-UI-Browser-Navigation
-    issues.
-* Cr-Privacy:  Privacy related bug (History, cookies discoverable by an entity
-    that shouldn't be able to do so, incognito state being saved in memory or on
-    disk beyond the lifetime of incognito tabs, etc).  Generally used in
-    conjunction with other labels.
-* Type-Bug-Security:  Security related bug (Allows for code execution from
-    remote site, allows crossing security boundaries, unchecked array bounds,
-    etc).
