No indexing IIS 6 Win 2003 Server
 

I spend many time to find out what the problems are with the NEW IIS 6 at Windows 2003 Server.

PHPDIG don´t indexing IIS 6 Websites at the moment.

I also try to index a IIS 6 Sites from a Linux-System - same result. (email me, I sent you the web-page to test it.)

Results of indexing:

I will also ask in a Win-Newsgroups to get the reasons for this.

I read some other problems with Error 400: does phpdig use allowed HTTP RFC Commands: see: RFC 2616

Hi. With HEAD [your_site]/robots.txt HTTP/1.1 it produces the following:

Content-Length: 24

The robots.txt file contains the following:
What happens if you just delete the robots.txt file?

What do you get?

ok is deleted. You can try again. Its just the same in my tests.

-Roland-

Hi. Please can you post the results like you did above? Maybe there will be something in there, or are the results just like those above?

Hmm, Monitor-Log is only possible if i start this 2 sec before i dig.

This is wrong - IMHO !!
robot_functions.php Line 286

The Header(lines) of the HEAD Requests are NOT split by CRLF only
with LF ('\n')? LF is wrong in RFC - Each header ends with a CRLF !!

See:
http://www.w3.org/Protocols/rfc2616/...c2.html#sec2.2

Hi. I believe the problem is that the script uses \n and your machine needs \r\n.

Please try this to fix the problem: First make a backup of the robot_functions.php file. Then in robot_functions.php, do the following:

1. find:
   
   
   PHP Code:

   ---

   $auth_string = 'Authorization: Basic '.base64_encode($components['user'].':'.$components['pass'])."\n"; 


   ---

   and replace with:
   
   
   PHP Code:

   ---

   $auth_string = 'Authorization: Basic '.base64_encode($components['user'].':'.$components['pass'])."\r\n"; 


   ---

2. find:
   
   
   PHP Code:

   ---

   $cookiesSendString .= "Cookie: ".$cookieString['string']."\n"; 


   ---

   and replace with:
   
   
   PHP Code:

   ---

   $cookiesSendString .= "Cookie: ".$cookieString['string']."\r\n"; 


   ---

3. find:
   
   
   PHP Code:

   ---

   @ini_set('user_agent','PhpDig/'.PHPDIG_VERSION.' (PHP; MySql)'."\n".phpDigMakeCookies($cookiesToSend,$path)); 


   ---

   and replace with:
   
   
   PHP Code:

   ---

   @ini_set('user_agent','PhpDig/'.PHPDIG_VERSION.' (PHP; MySql)'."\r\n".phpDigMakeCookies($cookiesToSend,$path)); 


   ---

4. find:
   
   
   PHP Code:

   ---

     $request =
  "HEAD $path HTTP/1.1\n"
  ."Host: $host$sport\n"
  .$cookiesSendString
  .$auth_string
  ."Accept: */*\n"
  ."Accept-Charset: ".PHPDIG_ENCODING."\n"
  ."Accept-Encoding: identity\n"
  ."User-Agent: PhpDig/".PHPDIG_VERSION." (PHP; MySql)\n\n"; 


   ---

   and replace with:
   
   
   PHP Code:

   ---

     $request =
  "HEAD $path HTTP/1.1\r\n"
  ."Host: $host$sport\r\n"
  .$cookiesSendString
  .$auth_string
  ."Accept: */*\r\n"
  ."Accept-Charset: ".PHPDIG_ENCODING."\r\n"
  ."Accept-Encoding: identity\r\n"
  ."User-Agent: PhpDig/".PHPDIG_VERSION." (PHP; MySql)\r\n\r\n"; 


   ---

5. find:
   
   
   PHP Code:

   ---

   $req1 = "HEAD $path HTTP/1.1\n"
."Host: $host$sport\n"
.$cookiesSendString
.$auth_string
."Accept: */*\n"
."Accept-Charset: ".PHPDIG_ENCODING."\n"
."Accept-Encoding: identity\n"
."User-Agent: PhpDig/".PHPDIG_VERSION." (PHP; MySql)\n\n"; 


   ---

   and replace with:
   
   
   PHP Code:

   ---

   $req1 = "HEAD $path HTTP/1.1\r\n"
."Host: $host$sport\r\n"
.$cookiesSendString
.$auth_string
."Accept: */*\r\n"
."Accept-Charset: ".PHPDIG_ENCODING."\r\n"
."Accept-Encoding: identity\r\n"
."User-Agent: PhpDig/".PHPDIG_VERSION." (PHP; MySql)\r\n\r\n";

I think that's all of them that absolutely need to be changed. I also think you could just do a search and replace, changing all \n to \r\n in the files.

As a general rule of thumb, I believe it's like this for different OS:

Windows uses \r\n
Macintosh uses \r
*nix uses \n

Ah, I see you were already thinking that. To test, I wrote a script to do a HEAD request on your machine. With only \n I received 400 Bad Request, but with \r\n it worked fine.

Thanks :)

I think it should change in the next Version it is conform to RFC - and if users update they can fix this again

I wrote above:

http://www.w3.org/Protocols/rfc2616/...c2.html#sec2.2

Microsoft IIS 6 is designed for NEW Security ;) and they use STRICT RFC and no tolerant applications.
