Thanks but I tried that. The problem is that the value of REMOTE_USER has no value. I use apache version 2.2 Here are the configuration: <Location /kongsberg> AuthType basic AuthName "LOS" AuthUserFile conf/LOSbasicauth.sec Require user u1 u2 u3 </Location> RewriteCond %{REMOTE_HOST} (.*) RewriteRule ^/kongsberg/(.*) http://aeoas02/LOS/kongsberg/%1/$1 [QSA,P,L] In the access_log I get: IPADDRESS - u1 [27/May/2009:16:03:25 +0200] "GET /kongsberg/ HTTP/1.1" 404 343 "-" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; WOW64; Trident/4.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30618; InfoPath.2; MS-RTC LM 8)" In the rewrite log I get: IPADDRESS - - applying pattern '^/kongsberg/(.*)' to uri '/kongsberg/' IPADDRESS - - RewriteCond: input='' pattern='(.*)' => matched IPADDRESS - - rewrite '/kongsberg/' -> 'http://krsoastest01/test/kongsberg//' IPADDRESS - - forcing proxy-throughput with http://aeoas02/kongsberg// I can't see the username in the rewrite log. I tried several options but no value in remote_user.
