Last change on this file since 57613 was 57613, checked in by vboxsync, 9 years ago

IPRT,UINetworkReply.cpp: Added RTPathGlob, a set of RTCrStoreCertAddWantedDir/File/Store, a RTCrStoreCertAddWantedFromFishingExpedition, RTCrStoreCertCheckWanted, RTCrStoreCertCount, RTFsIsCaseSensitive and RTFileOpenTemp. Reworked some RTHttp bits and UINetworkReply stuff - this needs testing.
