fatrat, wxdfast and openesb

Open-ESB download page is broken for a long time. Fortunately I found one link here - https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewFilteredProducts-SingleVariationTypeFilter. Then I tried to download it via FatRat and wxDFast. FatRat failed to process the link of open_esb-v2.zip, but wxDFast works fine.
