Hi, I have a web cluster and use mod_rewrite to forward request to cluster, according with type of request. There is a external program in directive RewriteMap to classify requests. My external program: ... while(1) { fscanf(stdin, "%s", input); // read input ---> format = /1, or /2, /3 ... sscanf(strchr(input,'/') + 1, "%d", &number); // extract only number of format switch(number) { case 1: fputs("192.168.1.11", stdout); break; case 2: fputs("192.168.1.22"); break; default: fprintf(stdout, "/bad_url"); break; } fputc('\n', stdout); fflush(stdout); ------------------------------------------------ My http.conf: RewriteEngine on RewriteLog /usr/local/apache2/logs/rewrite_log RewriteLogLevel 5 RewriteLock /usr/local/apache2/logs/file.lock RewriteMap prgmap prg:/usr/local/apache2/admControl RewriteCond ${prgmap:$1} !=/bad_url RewriteRule ^/(.*) http://${prgmap:$1}/ [P] RewriteRule ^(.*) - [F] My problem is, don't proxy request to cluster. See log file: (2) init rewrite engine with requested uri /1 (3) applying pattern '^/(.*)' to uri '/1' (5) map lookup OK: map=prgmap key=1 -> val= (4) RewriteCond: input='' pattern='!=/bad_url' => matched (5) map lookup OK: map=prgmap key=1 -> val= (2) rewrite '/1' -> 'http:///' (2) forcing proxy-throughput with http:/// (1) go-ahead with proxy request proxy:http:/// [OK] What's happen ??? Why mod_rewrite doesn't proxy requests to ip address ???
