/*
|
|
* How to create a new Channel, using NS_NewChannel,
|
|
* NS_NewChannelWithTriggeringPrincipal,
|
|
* NS_NewInputStreamChannel, NS_NewChannelInternal
|
|
* and it's variations:
|
|
*
|
|
* What specific API function to use:
|
|
* * The NS_NewChannelInternal functions should almost never be directly
|
|
* called outside of necko code.
|
|
* * If possible, use NS_NewChannel() providing a loading *nsINode*
|
|
* * If no loading *nsINode* is avaialable, call NS_NewChannel() providing
|
|
* a loading *nsIPrincipal*.
|
|
* * Call NS_NewChannelWithTriggeringPrincipal if the triggeringPrincipal
|
|
* is different from the loadingPrincipal.
|
|
* * Call NS_NewChannelInternal() providing aLoadInfo object in cases where
|
|
* you already have loadInfo object, e.g in case of a channel redirect.
|
|
*
|
|
* @param aURI
|
|
* nsIURI from which to make a channel
|
|
* @param aLoadingNode
|
|
* The loadingDocument of the channel.
|
|
* The element or document where the result of this request will be
|
|
* used. This is the document/element that will get access to the
|
|
* result of this request. For example for an image load, it's the
|
|
* document in which the image will be loaded. And for a CSS
|
|
* stylesheet it's the document whose rendering will be affected by
|
|
* the stylesheet.
|
|
* If possible, pass in the element which is performing the load. But
|
|
* if the load is coming from a JS API (such as XMLHttpRequest) or if
|
|
* the load might be coalesced across multiple elements (such as
|
|
* for <img>) then pass in the Document node instead.
|
|
* For loads that are not related to any document, such as loads coming
|
|
* from addons or internal browser features, use null here.
|
|
* @param aLoadingPrincipal
|
|
* The loadingPrincipal of the channel.
|
|
* The principal of the document where the result of this request will
|
|
* be used.
|
|
* This defaults to the principal of aLoadingNode, so when aLoadingNode
|
|
* is passed this can be left as null. However for loads where
|
|
* aLoadingNode is null this argument must be passed.
|
|
* For example for loads from a WebWorker, pass the principal
|
|
* of that worker. For loads from an addon or from internal browser
|
|
* features, pass the system principal.
|
|
* This principal should almost always be the system principal if
|
|
* aLoadingNode is null. The only exception to this is for loads
|
|
* from WebWorkers since they don't have any nodes to be passed as
|
|
* aLoadingNode.
|
|
* Please note, aLoadingPrincipal is *not* the principal of the
|
|
* resource being loaded. But rather the principal of the context
|
|
* where the resource will be used.
|
|
* @param aTriggeringPrincipal
|
|
* The triggeringPrincipal of the load.
|
|
* The triggeringPrincipal is the principal of the resource that caused
|
|
* this particular URL to be loaded.
|
|
* Most likely the triggeringPrincipal and the loadingPrincipal are
|
|
* identical, in which case the triggeringPrincipal can be left out.
|
|
* In some cases the loadingPrincipal and the triggeringPrincipal are
|
|
* different however, e.g. a stylesheet may import a subresource. In
|
|
* that case the principal of the stylesheet which contains the
|
|
* import command is the triggeringPrincipal, and the principal of
|
|
* the document whose rendering is affected is the loadingPrincipal.
|
|
* @param aSecurityFlags
|
|
* The securityFlags of the channel.
|
|
* Any of the securityflags defined in nsILoadInfo.idl
|
|
* @param aContentPolicyType
|
|
* The contentPolicyType of the channel.
|
|
* Any of the content types defined in nsIContentPolicy.idl
|
|
*
|
|
* Please note, if you provide both a loadingNode and a loadingPrincipal,
|
|
* then loadingPrincipal must be equal to loadingNode->NodePrincipal().
|
|
* But less error prone is to just supply a loadingNode.
|
|
*
|
|
* Keep in mind that URIs coming from a webpage should *never* use the
|
|
* systemPrincipal as the loadingPrincipal.
