You can scan a big file partially and find viruses. It makes no sense for a gateway to scan hundreds of megs. Though I'm slightly partial (I develop it), I recommend you look into HAVP (http://www.server-side.de/). It has much more features, supports multiple scanners etc. >Im have one quiestion >Whether I can make similar ACL? >Example: >Acl size url_regex_filelenght =<1mb :) It's impossible to know real lenght of incoming data, until it's received. HAVP takes this carefully in consideration. >#acl stream url_regex -i .mp3 .vqf .avi .mpeg .mpe .mpg .qt .ram .rm .raw >.wav .mov .wmv .htm .html .gif .jpg .jpeg >#acl progs url_regex -i .exe .scr >.com .dat .rar .zip .cmd .vbs .vba .jar .386 .bin .dll .drv .pif .txt .doc >.xls .ppt .rtf .pps .sys .vxd .vst .php .cab .ms Also it's impossible to identify content based on URL. HAVP scans everything, it's the only possible secure way. But streaming is handled separately and you can whitelist images if you are very short on CPU. Cheers, Henrik
