It can generate a log with IP addresses and the information whether it can be a proxy. Rex v1.1 features: - Proxy port scan can be disabled (in some cases, it blocks users that have port 80 open in their router configuration) - Added checkspamcop() that checks if a user IP is registered as spammer on Spamcop.net (can be enabled/diabled) - Function filtraxss() renamed to checkxss() because it really checks the presence of malicious xss doesn't filter anything - Function checkxss() only accepts arrays - Added filterxss() that removes or disables tags - Added checksize_db_data() that can be used to check for data size before inserting in database - Added filtersql() that escapes special characters in a string for use in a SQL statement
