Rename chrome.experimental.webRequest to chrome.webRequest
Note that this CL also introduces a new permission webRequestBlocking that is required in addition to webRequest if you want to use blocking request handlers.

This ID is unique within a +browser session and the context of an extension. It remains constant during the +the life-cycle of a request and can be used to match signals for the same +request. Note that several HTTP requests are mapped to one webRequest in case of +HTTP redirection or HTTP authentication.</p> + +<h3 id="subscription">Subscription</h3> + +<p>For each signal XXX of the webRequest API, the API provides a function +<code>chrome.webRequest.XXX.addListener()</code> with the following +signature.</p> + +<pre>var callback = function(details) {...}; +var opt_filter = {...}; +var opt_extraInfoSpec = [...]; + +chrome.webRequest.XXX.addListener( + callback, opt_filter, opt_extraInfoSpec); +</pre> + +<p>Each <code>addListener()</code> call takes a mandatory callback function as +the first parameter. This callback function is passed a dictionary containing +information about the current URL request. The information in this dictionary +depends on the specific event type as well as the content of +<code>opt_extraInfoSpec</code>.</p> + +<p>If the optional <code>opt_extraInfoSpec</code> array contains the string +<code>'blocking'</code> (only allowed for specific signals), the callback +function is handled synchronously. That means that the request is blocked until +the callback function returns. In this case, the callback can return a <a href="#type-BlockingResponse">BlockingResponse</a> that determines the further +life-cycle of the request. Depending on the context, this response allows +cancelling or redirecting a request (onBeforeRequest), cancelling or +modifying headers (onBeforeSendHeaders, onHeadersReceived), or providing +authentication credentials (onAuthRequired).</p> + +<p>Depending on the specific signal, <code>opt_extraInfoSpec</code> may contain +further strings that indicate that specific information shall be passed to the +extension. This is used to provide detailed information on requests data only if +explicitly requested.</p> + +<p>The optional <a href="#type-RequestFilter">RequestFilter</a> +<code>opt_filter</code> allows to limit the requests for which events are +triggered in various dimensions: +</p><dl> + <dt>URLs</dt> + <dd>URL patterns like <code>*://www.google.com/foo*bar</code>.</dd> + <dt>Types</dt> + <dd>Request types like <code>main_frame</code> (a document that is loaded for + a top-level frame), <code>sub_frame</code> (a document that is loaded for an + embedded frame), <code>image</code> (an image on a web site) and others.

If +an extension cancels a request, all extensions are notified by an +onErrorOccurred event. Only one extension is allowed to redirect a request or +modify a header at a time. If more than one extension attempts to modify the +request, the most recently installed extension wins while all others are +ignored. An extension is currently not notified, if its instruction to modify or +redirect has been ignored.</p> + +<a name="H2-6"></a><h2>A note about caching</h2> +<p> +Chrome employs two caches, an on-disk cache and a very fast in-memory cache. +The life-time of an in-memory cache is attached to the life-time of a render +process which roughly corresponds to a tab. Requests that are answered from the +in-memory cache are invisible to the webRequest API. If a request handler +changes its behavior (for example the behavior according to which requests are +blocked), a simple page refresh might not respect this changed behavior. +<code>chrome.webRequest.handlerBehaviorChanged()</code> needs to be +called to flush the in-memory cache. This is a very expensive operation and +should not be done often. +</p> + +<a name="H2-7"></a><h2>A note about timestamps</h2> +<p> +It's important to note that some technical oddities in the OS's handling +of distinct Chrome processes can cause the clock to be skewed between the +browser itself and extension processes. That means that WebRequest's events' +<code>timeStamp</code> property is only guaranteed to be <i>internally</i> +consistent. Comparing one event to another event will give you the correct +offset between them, but comparing them to the current time inside the +extension (via <code>(new Date()).getTime()</code>, for instance) might give +unexpected results. +</p> + +<h2 id="examples">Examples</h2> + +<p>The following example illustrates how to block all requests to +<code>www.evil.com</code>:</p> +<pre>chrome.webRequest.onBeforeRequest.addListener( + function(details) { + return {cancel: details.url.indexOf("://www.evil.com/") != -1}; + }, + {}, + ["blocking"]); +</pre> + +<p>As this function uses a blocking signal handler, it requires the "webRequest" +as well as the "webRequestBlocking" permission in the manifest file.</p> + +<p>The following example achives the same goal in a more efficient way because +requests that are not targeted to <code>www.evil.com</code> do not need to be +passed to the extension:</p> +<pre>chrome.webRequest.onBeforeRequest.addListener( + function(details) { return {cancel: true}; }, + {urls: ["*://www.evil.com/*"]}, + ["blocking"]); +</pre> + +<p>The following example illustrates how the User-Agent header can be deleted +from all requests:</p> +<pre>chrome.webRequest.onBeforeSendHeaders.addListener( + function(details) { + delete details.requestHeaders['User-Agent']; + return {requestHeaders: details.requestHeaders}; + }, + {}, + ["blocking"]); +</pre> + +<!-- +TODO(mkwst): update this section.
