|
|
* 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
|
|
* @param aLoadingPrincipal
|
|
* @param aTriggeringPrincipal
|
|
* @param aSecurityFlags
|
|
* @param aContentPolicyType
|
|
* These will be used as values for the nsILoadInfo object on the
|
|
* created channel. For details, see nsILoadInfo in nsILoadInfo.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.
