you can set a target="" for your form - so you could submit your form to a new tab (target="_blank") or to a small, hidden iframe (target="nameofmyiframe")

Change the target attribute of the form to the name of some hidden iframe.

If file uploading isn't required

Use any element that pulls its content from an external resource

<img src="server.php?name=JohnDoe" />
<link href="server.php?name=JohnDoe" rel="stylesheet" />
<script src="server.php?name=JohnDoe"></script>
