title: Call jQuery script located at server (and referanced by client) works on IE not FF and not Chrome
body: <p>I have the following situation, i have a service project (ASMX) and a web project (ASPX) which i run localy on ASP.NET Development Server.</p>
  
  <p>I have a jQuery script that contain a handfull of functions which is calling the local asmx service (hence, the jQuery script is on the service project /Scripts - doing some database insertion and update.</p>
  
  <p>on my client page i referance the following:</p>
  
  <pre><code> //Referance from client
   &lt;script src="Scripts/jquery-1.3.1.js" type="text/javascript"&gt;&lt;/script&gt;
   //Referance from service project
   &lt;script src="http://localhost:4000/Scripts/Default.js" type="text/javascript"&gt;&lt;/script&gt;
   //Referance from client
   &lt;script src="Scripts/Caller.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>using the caller.js i should be able to call Default.js functions without cross-domain issues as the file is located beside the service. Which is working but only in IE7 and IE8. however in Chrome and FireFox 3 it didn't work returing the following exception:</p>
  
  <p>[Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.send]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: <a href="http://localhost:4906/Scripts/jquery-1.3.1.js" rel="nofollow noreferrer">http://localhost:4906/Scripts/jquery-1.3.1.js</a> :: anonymous :: line 3511"  data: no]</p>
  
  <p>and on FireBug i get:
  <strong>Access to restricted URI denied" code: "1012</strong></p>
  
  <p>After some googling this turn'ed out related to some Security Model - Cross-Domain blocking, which is weird as it works on IE and i don't think i am doing any Cross-Domain here as mentioned above the default.js (Which contains the calls to service) is located on the service project/server.</p>
  
  <p><strong>Summery:
  When referancing a script file that is located on the server any calls from a client that referance that file producing this error.</strong></p>
  
  <p>My Ajax Call is below:
  function PingJSON(fname,lname,family) {
   //Preparing Parameters and output
      var id='empty_response';
      var params = "{x:'" + fname + "',y:'" + lname+  "',z:'"+ family + "'}";</p>
  
  <pre><code>//jQuert Ajax Call
  $.ajax({
      type: "POST",
      url: "http://localhost:4000/MyService.asmx/PingService",
      data: params ,
      timeout: 10000,
      async:false,
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(msg) { //Success callback function
          id = msg;
      },
      error: function(xhr, ajaxOptions, thrownError) { //Fail callback function
          alert(xhr.status);
          alert(thrownError);
      }
  });
  return id;
