Javascript XMLHttpRequest POST

[mudders]

Hi,

I've been testing a page on my local machine and part of it passes a very long string (4000+ chars) to a php script. Using GET this fails. However on my local machine POST works. As soon as I upload it to the server it does not work and cannot seem to find the php file. Instead it seems to redirect to the domain root index file.
I do not have an .htaccess file in the directory where I am running this page from and I have commented out all entries in my root .htaccess.

See the code below - in this case I have simplifed it to only be posting a very short parameter but it does the same thing.

loadXMLDocTEST("saveRouteTEST.php");

function loadXMLDocTEST(url) {
  xmlhttp=null;
  if (window.XMLHttpRequest) {// code for all new browsers
    xmlhttp = new XMLHttpRequest();
  }
  else if (window.ActiveXObject) {// code for IE5 and IE6
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
  }
  if (xmlhttp != null) {
  
    var params = "route1=sd";
    
    xmlhttp.onreadystatechange = callBackTEST;
    xmlhttp.open("POST",url,true);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.setRequestHeader("Content-length", params.length);
    xmlhttp.setRequestHeader("Connection", "close");
    xmlhttp.send(params);
    
  }
  else {
    alert("Your browser does not support XMLHTTP.");
  }
}

function callBackTEST() {
  if (xmlhttp.readyState==4) {// 4 = "loaded"
    if (xmlhttp.status==200) {// 200 = OK
      //alert(xmlhttp.responseText);
      alert(xmlhttp.responseText);
      
    }
    else {
      alert("Problem retrieving XML data");
    }
  }
}

I can run a very similar script which uses GET and it works fine and finds my php file with no problems so to me it seems there is an issue with the POST.
Anyone got any ideas? Is POST blocked by the servers?

Thanks,

Mudders

i'm not really up on XMLHttpRequest as i had problems trying to use it successfully with F|lex, but what is being returned from your script? Is the XML well formed?

Hi,

At this stage its not even seeing my script. the php script just prints out "Done...". Thats it.
But the return value I'm getting is the output of the index.html file at the root of the domain.

I've since figured out that this problem seems to be Firefox3 specific. I've been doing all my testing on Firefox3 and then I tried it in IE and Firefox2 and it works in both those browsers so seems to be a browser specific issue.
