Hello ! 2006/12/20, olivier nouguier <[EMAIL PROTECTED]>:
1) How do you submit your forms ... a few years ago I had a guy who show my that "issue", in fact he submitted the form "oncheck" on an input image ...
No, just <html:form> and <hmtl:submit> 2a) There is a simple server side pattern two avoid double submit:(could not
find the www reference). * jsp put a token in the session (scriplet, taglib). * submit action test the token and remove it from the session. so the second post can safely fail as the token is not found !
Ok, thanx ! I've found a description in this page : http://www.jax-magazine.com/itr/online_artikel/psecom,id,648,nodeid,147.html look for "Handle duplicate form submission" Thanx again & regards, Pierre **
