Comment:

 Hi,

 I can confirm that I am seeing the same issues and have done for a while,
 certainly from 3.9.1 onwards which fundamentally means that some users
 (particularly behind Squid proxies) are effectively unable to update core,
 plugins or themes in the normal manner.

 Commenting 9 lines of code (the 3 instances) is certainly a temporary fix,
 but is not optimal as when a WP upgrade takes place this will get
 trampled.

 I do have an alternative suggestion and that is to make these three URL
 scheme re-writes sit behind a configuration option, such as
 WP_PROXY_SUPPORTS_HTTPS_POST; so at least then it is a configurable
 option.

 Is there any timescale on a permanent fix for this?

 Thanks

 Paul
