How about this: <a href="image.jsp?mult=1" id='submitButton1' onclick="return false;" class="buttonRedSmall"><span>Submit Form</span></a> BTW, the default target is "_self", so there's no need to specify that. Unless there is more Javascript that you haven't posted, the above does not submit a form. > And causes the multiple form submits. How to prevent the same ?

Note that this isn't exactly an "attack". - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkvxogEACgkQ9CaO5/Lv0PAz4QCbBtTKYrr0tUk2dDckWbQ3L6yD NtAAn034OtDLMa9IF+NO7VOVgfpS/eKg =yKxU -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
