google and php script 301's

[rremm2000]

Hello thanks for reading my question

For some reason 2 days ago good and all the other bots suddenly starting hitting my site like

 http://mysite.com/ bla bla bla

I have a security feature that I have installed in my header file that does the follow and this has been for a year or two now

    IF ( strcmp( $_SERVER['HTTP_HOST'],'www.mytestsite.com') == 0 ) { #Test/Live Server Configs
         #-- [ PHP ERRORS ] set error reporting level
         error_reporting( E_ERROR | E_WARNING | E_PARSE  ); // ADD | E_NOTICE
         $site['url']      = "http://www.mytestsite.com/";
         $site['url_main'] = "http://www.ia-swingerstest.com/";
         $site['title']    = "Test V41";
         $dir['root']      = "/home3/public_html/info/";
         $dir['inc']       = "/home3/includefiles/";
         $admin_dir        = "admin";
         $moderator_dir    = "moderators";
         $TestServer = TRUE;
         DEFINE('JOIN_EN', FALSE ); # Enable Join with TRUE
    }ELSEIF( strcmp( $_SERVER['HTTP_HOST'],'www.mymainsite.com') == 0 ) {
         $site['url']      = "http://www.www.mymainsite.com/info/";
         $site['url_main'] = "http://www.www.mymainsite.com/";
         $site['title']    = "Community";
         $dir['root']      = "/home/public_html/info/";
         $dir['inc']       = "/home/incfiles/";
         $admin_dir        = "admin";
         $moderator_dir    = "moderators";
         $TestServer = FALSE;
         DEFINE('JOIN_EN', TRUE ); # Enable Join with TRUE
    }ELSE{

         DIE( "Illegal proxy access or hacking attempt, contact the admin of this site!" );

         EXIT;
    }

I don't know but some body may have linked to my site with the
http://mysite.com

So is there ANY draw back to do this

        IF ( strcmp( $_SERVER['HTTP_HOST'],'www.mytestsite.com') == 0 ) { #Test/Live Server Configs
             #-- [ PHP ERRORS ] set error reporting level
             error_reporting( E_ERROR | E_WARNING | E_PARSE  ); // ADD | E_NOTICE
             $site['url']      = "http://www.mytestsite.com/";
             $site['url_main'] = "http://www.ia-swingerstest.com/";
             $site['title']    = "Test V41";
             $dir['root']      = "/home3/public_html/info/";
             $dir['inc']       = "/home3/includefiles/";
             $admin_dir        = "admin";
             $moderator_dir    = "moderators";
             $TestServer = TRUE;
             DEFINE('JOIN_EN', FALSE ); # Enable Join with TRUE
        }ELSEIF( strcmp( $_SERVER['HTTP_HOST'],'www.mymainsite.com') == 0 ) {
             $site['url']      = "http://www.www.mymainsite.com/info/";
             $site['url_main'] = "http://www.www.mymainsite.com/";
             $site['title']    = "Community";
             $dir['root']      = "/home/public_html/info/";
             $dir['inc']       = "/home/incfiles/";
             $admin_dir        = "admin";
             $moderator_dir    = "moderators";
             $TestServer = FALSE;
             DEFINE('JOIN_EN', TRUE ); # Enable Join with TRUE
        }ELSE{
             $CURL = 'http://www.mymainsite.com' . $_SERVER['REQUEST_URI'];
             header ("HTTP/1.1 301 Moved Permanently");
             header ("Location: $CURL");
             DIE( "Illegal proxy access or hacking attempt, contact the admin of this site!" );

         EXIT;
    }

basically adding
$CURL = 'http://www.mymainsite.com' . $_SERVER['REQUEST_URI'];
header ("HTTP/1.1 301 Moved Permanently");
header ("Location: $CURL");
if the string compare fails

Why would the bots suddenly start crawling my site with http://mysite.com rather than the orignal http://www.mysite.com it all happend in one day

Why are you limiting your users from visiting the "actual" domain? Why are you forcing them to use the virtual "www" domain? I personally type a web address without the leading "www" since it's essentially a given. You could also just add a simple test before anything which prepends the "www" if it's not already there.

I don't know why they switched, but perhaps you should bring your code up to be able to handle that by redirecting users to the "www" virtual domain or just add it yourself in your code for them.

well mainly I found a lot of online proxy services will browse through sites using the http://site.com so to prevent them from using those types of services on my site I force the www with the 301 redirect.
won't this part force the www and do it without them having to type it in
header ("HTTP/1.1 301 Moved Permanently");
header ("Location: $CURL");

[bpat1434]

It should. The way to test is to put it up and then you yourself visit the site with out the "www" in front and then see if you get forwarded.

I'm not 100% sure that all proxies would heed the 301 error though. So this might not be a full-proof plan. I'm still not understanding why you want to keep proxies out, or why you want to ostracize them specifically.
