/*
* 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.
