[TYPO3-v4] Using t3lib_div::getUrl() also for xml.gz files from Extension Manager?

Exactly, proxies wouldn't be an issue here. So maybe actually using 
file_get_contents() directly might be ok, but I don't know if it's part 
of the functions that may be blocked per PHP configuration (like fopen 
or fsockopen).

I didn't think about that. It's true that it would take some additional 
memory. Maybe it's then worth testing if XMLReader::open() has been 
successful or not and call t3lib_div::getURL() as a fall back. It 
introduces an additional test, but I guess it's not an issue in this case.

Cheers
