spring - CSRF protection in Tomcat 7 -


how can prevent csrf protection using tomcat 7 ?

i have heard tomcat 7 provides csrf filter http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/filters/csrfpreventionfilter.html

but thread safe ?

or shall custom protection in our spring 3 application ?

csrfpreventionfilter way prevent csrf attacks, altough it's part of tomcat code base , based on putting token in url.

this means token logged etc, it's better put token in hidden field in each form of page.

spring security 3.2 have built-in support, , solution work in other application servers. depending on application there no need building custom protection @ spring level, tomcat solution works ok.

the tomcat filter thread-safe, given each http request handled beginning end 1 thread, , token cache has synchronized access.
