RConvlog - CONVLOG replacement

Rebex Internet Log Converter converts web server log files from a native log format into NCSA format.

RConvlog (Rebex Internet Log Converter) converts web server log files from a native log format into NCSA format. It can be very useful especially when you use a log analyzer which does not support a native IIS format or a W3C Extended format (e.g. excellent Webalizer).

IIS is shipped with a similar program called convlog, which is able to convert web server log files into NCSA format. However using Microsoft convlog causes some problems: original convlog does not transfer browser agents and referrers. When used with FTP log files, all uploaded files are ignored.

RConvlog deals with all those difficulties.

Features

converts web server log files from IIS to NCSA format
runs on Windows, Linux and FreeBSD
supports browser agents
supports referrers
when used with FTP log files both uploads and downloads are logged (Microsoft's version converts only download)
a call format is compatible with Microsoft convlog. RConvlog can in most cases be used as an out-of-the-box replacement or a bugfix release of the original ;-)
a powerful and efficient DNS lookup and a caching mechanism
