1. NCSA httpd_1.4.2 following index.html symlink

I just upgraded from NCSA httpd_1.3 to 1.4.2 and found that it still has
a problem that I noted in the earlier version.  Namely, even with Options None
in the access.conf, it will follow a symlink'd index.html file.  It's
important to me that our server never follow symlinks because I want to
keep WWW file access restricted to a certain area of the system.

My solution is to add some lines to httpd_get.c:

*** http_get.c  Sun Sep 24 12:31:39 1995
--- http_get.c.orig     Fri Jun 23 12:09:57 1995

          }
          else {
- /*
-  * copied the following from above to prevent using index.html
-  * if it is a symlink.  Changed `file' args to `ifile'.   R. Perry, 9/24/95
-  */
-     evaluate_access(ifile,&finfo,M_GET,&allow,&allow_options, fd);
-     if(!allow) {
-         log_reason("client denied by server configuration",ifile);
-         unmunge_name(ifile);
-         die(FORBIDDEN,ifile,fd);
-     }
-
              probe_content_type(ifile);
              if(!strcmp(content_type,CGI_MAGIC_TYPE))
                  send_cgi("GET",ifile,pa,args,&finfo,in,fd);
