Hi,
I am not big on JavaScript (I usually do Java/JSPs), however I am trying to create a solution to the below problem using JavaScript (it is something Java cannot do):
I need to send a request to a url with a custom header in the http request, the response will be of type “application/x-ica” and will return an ica file. All I need to do is launch the citrix application (ica files give you the information you need to do this) as per usual way of dealing with ica files by internet explorer on the client machine.
I havent found a way of submitting an http request with javascript and then telling the browser to deal with the reponse as it normally would (i.e. launch citrix), the response goes into an ‘XMLHttpRequest’ object. I’m not sure how to get the browser to take the reponse and deal with it and launch the citrix application.
I know this is possible by saving the response to a file, then opening the file with something like:
[CODE]function run()
{
var file = “C:\Documents and Settings\jdevine5\Desktop\appica.ica”;
var ws = new ActiveXObject(“WScript.Shell”);
ws.run(“”C:\Program Files\Citrix\ICA Client\wfica32.exe” “C:\Documents and Settings\jdevine5\Desktop\appica.ica””);
}
however for security reasons this isnt an option.
Can anybody suggest a better way of doing this?
For reference my code so far is below (it’s only a test harness, this isn’t the real solution but it replicates the crucial bit):
[CODE]<html>
<body>
<script type=”text/javascript”>
function makeHttpObject()
{
try {return new XMLHttpRequest();}
catch (error) {}
try {return new ActiveXObject(“Msxml2.XMLHTTP”);}
catch (error) {}
try {return new ActiveXObject(“Microsoft.XMLHTTP”);}
catch (error) {}
throw new Error(“Could not create HTTP request object.”);
alert(“blah”);
show(typeof(makeHttpObject()));
}
function go()
{
var url = “http://100.100.100.100:8011/app/servlet?param1=9999”;
var headervar = “token_text”;
var request = makeHttpObject();
request.open(“GET”, url);
request.setRequestHeader(“X-custom”, headervar);
request.send(null);
request.onreadystatechange = function() {
if (request.readyState == 4)
document.write(request.responseText);
};
}
</script>
<input type=”button” value=”MAKE HTTP REQUEST” onclick=”go();”><br><br>
</body>
