> We recently tried to update from 2.3.16.3 to 2.3.4.1  based on 
> https://struts.apache.org/docs/s2-026.html, we are hitting regressions issues due to a change in CookieInterceptor.  
> It's currently using the same accepted_pattern to check out both name & value to pass around the cookies. When the cookie values are simple, it works.  When the cookie value carries a special chars for example a url is the cookie value, it fails with the existing pattern and it is not passed to actions. 
> I didn't find a way getting around this in the config and this has been a blocker for us to update to the version.
> Why are we checking for cookie values with the same hardcoded pattern only ?  If there is a way to workaround this in the config? 
>     private static final String ACCEPTED_PATTERN = "[a-zA-Z0-9\\.\\]\\[_'\\s]+";
>     .....    
> protected boolean isAcceptableValue(String value) {
>         return !isExcluded(value) && isAccepted(value);
>     }
