Proxy Server (Delegate)

Updated on 18th Oct 2003

DeleGate is a multipurpose proxy server which relays various application protocols on TCP/IP or UDP/IP, including HTTP, FTP, Telnet, NNTP, SMTP, POP, IMAP, LPR, LDAP, ICP, DNS, SSL, Socks, and more. DeleGate mediates communication between servers and clients where direct communication is impossible, inefficient, or inconvenient.

Comparison with Microsoft Internet Security and Acceleration (ISA) Server 2000

This is the reason why I don't use ISA and suggesting Delegate.

\	Microsoft ISA Server 2000	Delegate
Price	Enterprise Edition costs $5,999 US per processor Standard Edition costs $1,499 US per processor	Free
OS	Windows 2000 Server costs $1,199 per server Windows 2000 Advanced Server costs $3,999 per server	Multiple platforms (all Unix, all Windows and OS/2)
Program Size	CD	Less than 1 Floppy
Stability	The server should be restarted frequently (once for few days at least)	No maintenance required

Install Delegate

Download Delegate (delegate.zip) from http://www.delegate.org/delegate/

Extract delegate.zip and copy files to appropriate directory. In this example, the files are under C:\Program Files\delegate\dg8_4_0.exe ...

Make install.bat file as below, execute and install as a service.

Example

dg8_4_0.exe -P8080 ADMIN="hoge@hoge.com" DGROOT="C:\Program Files\delegate" EXPIRE=7d CRON="0 * * * * -expire 7d" CACHE=do REMITTABLE="*" LOGFILE=""

Log file LOGDIR and LOGFILE function with date options do not work for Windows version of delegate(ver 8_4_0). So the log files will grow unless you remove manually. If you do not want to remove manually, put this option and do not log! LOGFILE=""
