multiple form submits

[Karthik Nanjangude]

Hi

Spec :
JDK1.5
TOMCAT 6.0.20
O/s windows /Linux


Question  :     My web application uses "href" & "css based image's"   for  
transferring the request from 1 page to another
                   The problem is UserVisitor is  clicking the image based href 
 MULTIPLE TIMES ( multiple clicks )

<a href="image.jsp?mult=1" id='submitButton1'  
onClick="this.onclick=function(){return false}" target="_self"
                   class="buttonRedSmall"><span>Submit Form</span></a></td>

And causes the multiple form submits.  How to prevent the same ?

I googled / yahooed for Cross browser based  tricks to disable the multiple 
request...Not luck so far ...

Can some body help me if Tomcat has any special features to prevent this attack 
....... :(




with regards
