Compare batch

my script for quick comparing. Sometimes easier than using winmerge.

@echo off
diff -u 1.txt 2.txt > 12.diff

JQuery Ajax cross domain request

If you try to do an ajax request on a different domain. You’ll get nothing. Looking a bit deeper into the request I noticed that the status code isn’t 200 or 403 nor 404 like expected. Nope it is 0. (jquery ajax statusCode 0). This means the browser doesn’t allow a crossdomain request. The easiest way for me to solve this was to create a proxy php script. Now I can send my ajax request to a url on my server while the PHP script does the real request to the other server.

This is the php script

/**
* GetFromHost()
*
* @param string $host
* @param int $port
* @param string $path
* @param string $referer
* @param bool $keepalive
* @return
*/
function GetFromHost($host, $port, $path, $referer,$keepalive=false) {

 $fsocket = fsockopen($host, 80, $errno, $errstr, 30);

 if($fsocket){
 $request =     "GET $path HTTP/1.1\r\n";
 $request .= "Host: $host\r\n";
 $request .= "Referer: $referer\r\n";
 $request .= 'User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) ';
 $request .= "Gecko/20021204\r\n";
 $request .= 'Accept: text/xml,application/xml,application/xhtml+xml,';
 $request .= 'text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,';
 $request .= "image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1\r\n";
 $request .= "Accept-Language: en-us, en;q=0.50\r\n";
 //$request .= "Accept-Encoding: gzip, deflate, compress;q=0.9\r\n";
 $request .= "Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66\r\n";
 if($keepalive==true){
 $request .= "Keep-Alive: 300\r\n";
 $request .= "Connection: keep-alive\r\n";
 }
 else
 {
 $request .= "Connection: close\r\n";
 }
 //$request .= "Content-Type: application/x-www-form-urlencoded\r\n";
 //$request .= "Content-length: ". strlen($data_to_send) ."\r\n";
 $request .= "\r\n";
 //$request .= $data_to_send;

 fputs($fsocket, $request);

 $res ='';
 while(!feof($fsocket)) {
 $res .= fgets($fsocket, 1024);
 }
 fclose($fsocket);

 return $res;

 }
 else
 {
 return false;
 //echo "Fehlgeschlagen: ".$fsocket . $host .':'. $port;
 }

}

$x = GetFromHost("www.example", "80", "/deep/url/kinda/", "");
$x = explode('Content-Type: text/html',$x);
$output = preg_replace('/\s+(\r\n|\r|\n)/', '$1', $x['1']);//remove white space and tabs at the line ends
echo $output;

maybe you have to edit the explode part for server to separate the header fom the real content.

Scroll console output on FreeBSD

People coming from Linux will find that they can’t scroll back through the console output the same way on FreeBSD.

In FreeBSD you need to press “Scroll Lock” and use the arrow keys, PageUp and PageDown to be able to scroll backwards and forwards the console output. To go back to the prompt press “Scroll Lock” again.

RedDot release page without plugin but in the page

Today I had the issue to release a page without able to access the file system and creating a plugin for that which would be nicer.  But it also works inside the content template class. it is no ideal, but it works and reloads the page.

<script language="javascript">
function release_page(){
	location.href='ioRD.asp?Action=ReleasePage&EditLinkGuid=<%PageGUID%>';
	location.reload();
	return  true;
}
</script>

<a href="#" onclick="release_page();"><img border="0"  src="Icons/Release.gif"></a> release snippet
