Coldfusion - How to prevent multiple clicks?

Question

I have a button (anchor tag) that send a confirm message if you press it. The problem is that for example if you press it 5 times very quickly it will send 5 confirm messages, if you press it 2 times it will send 2 messages.

This can occur when the user has low connection speed and while the page is refreshing he presses again the button.

How can I manage this situation? I though of disabling the button but for other reasons this is not possible.

<a class="msg" href="/manage/conversations.cfm?destination=#destination#">
        #ucase(request.l('Send'))#
</a>

Thank you for your time

Ultimately, you need to have code on your server to prevent processing the link multiple times from the same user.

However, to solve the UI issue, have you link call a function instead of the cf file directly.

<a class="msg" href="javascript: processLink(#destination#);">
        #ucase(request.l('Send'))#
</a>

<script>
runCount = 0;

function processLink(destination){
runCount++;

if (runCount == 1){
 window.location.href = "/manage/conversations.cfm?destination=" + destination;
}

}
</script>
