/*
|
|
* The nsSecCheckWrapChannelBase wraps channels that do *not*
|
|
* * provide a newChannel2() implementation
|
|
* * provide get/setLoadInfo functions
|
|
*
|
|
* In order to perform security checks for channels
|
|
* a) before opening the channel, and
|
|
* b) after redirects
|
|
* we are attaching a loadinfo object to every channel which
|
|
* provides information about the content-type of the channel,
|
|
* who initiated the load, etc.
|
|
*
|
|
* Addon created channels might *not* provide that loadInfo object for
|
|
* some transition time before we mark the NewChannel-API as deprecated.
|
|
* We do not want to break those addons hence we wrap such channels
|
|
* using the provided wrapper in this class.
|
|
*
|
|
* Please note that the wrapper only forwards calls for
|
|
* * nsIRequest
|
|
* * nsIChannel
|
|
* * nsIHttpChannel
|
|
* * nsIHttpChannelInternal
|
|
* * nsIUploadChannel
|
|
* * nsIUploadChannel2
|
|
*
|
|
* In case any addon needs to query the inner channel this class
|
|
* provides a readonly function to query the wrapped channel.
