Re: Module that forward requests
Hi, Yesterday, I studied mod_rewrite very much and I believe that fully_qualify_uri() function is where mod_rewrite does proxy. That's right ?? This is way ?? Other question, I copied fully_qualify_uri() function, but when print value r->filename give error: For example, in code: r->filename = apr_psprintf(r->pool, "%s://%s%s%s%s", "http", "ip_machine", "port_machine", r->filename); ap_log_error(APLOG_MARK, APLOG_CRIT, rv, ap_server_conf,"MEU_MODULE PROXY: %s", r->filename); In error_log shows: MEU_MODULE PROXY: http://ip_machine:port_machine(null)\x18#W\xb7[$\x07\bHl\xef\t\xd4m\xef\t\xdcm\xef\t\x04\n\xef\t What's this ?

Hi, I'm studying proxy in mod_rewrite and I saw the following line: request_rec *r; r->proxyreq == PROXYREQ_PROXY; But in httpd.h, the request_rec object hasn't field proxyreq. What's this ??
