proxy.RequestDetails

Contains information about a web request. An instance of this object is passed into the proxy.onRequest listener.

Type

Values of this type are objects. They contain the following properties:

cookieStoreId

string. The cookie store ID of the current context.

documentUrl

string. URL of the page into which the requested resource will be loaded.

frameId

integer. Zero if the request happens in the main frame; a positive value is the ID of a subframe in which the request happens. If the document of a (sub-)frame is loaded (type is main_frame or sub_frame), frameId indicates the ID of this frame, not the ID of the outer frame. Frame IDs are unique within a tab.

fromCache

boolean. Indicates if this response will be fetched from disk cache.

incognito

boolean true for private browsing requests.

method

string. Standard HTTP method: for example, "GET" or "POST".

originUrl

string. URL of the resource that triggered the request. Note that this may not be the same as the URL of the page into which the requested resource will be loaded. For example, if a document triggers a load in a different window through the target attribute of a link, or a CSS document includes an image using the url() functional notation, then this is the URL of the original document or of the CSS document, respectively.

parentFrameId

integer. ID of the frame that contains the frame that sent the request. Set to -1 if no parent frame exists.

requestId

string. The ID of the request. Request IDs are unique within a browser session, so you can use an ID to identify different events associated with the same request.

requestHeadersOptional

webRequest.HttpHeaders. The HTTP request headers that will be sent with this request. Note that this is only included if the "requestHeaders" option was passed into addListener().

tabId

integer. ID of the tab in which the request takes place. Set to -1 if the request is not related to a tab.

thirdParty

boolean. Indicates whether the request and its content window hierarchy is third party.

timeStamp

number. The time when this event fired, in milliseconds since the epoch.

type

webRequest.ResourceType. The type of resource being requested: for example, "image", "script", or "stylesheet".

url

string. Target of the request.
