GS_Serv-U_Xunlei_Immune is a plug-in based on Serv-U. GSSXI can identify FTP requests initiated by Xunlei (including Web Xunlei) and process Xunlei's requests according to different situations. This plug-in can effectively prevent Xunlei from downloading resources on your FTP server, which greatly reduces the pressure Xunlei puts on your FTP server.
