Dynamically creating a .js file to be included in response

[Ron Vecchi]

I am creating a custom web control that uses an enum for a property
{Remote,InLine}.
If the property is set to inline then text is read from the embedded
resource and sent to the browser in the aspx page as inline java script.
If the property is set to Remote then the script tag set with the SRC
attribute is displayed <script language="javascript"
Src="MyJS.js"></script>.

Is there a way to catch an incoming request from the browser (for the
<script language="javascript" src="myJavaScript.js"></script>
And then dynamically create the file before it returns a response to the
browser that the file does not exsit
Thanks,
Ron.
