Would it be sufficient to make sure that input strings (WOStrings) have escapeHTML = true? or is it better to just strip HTML ourselves?
The wiki says: If you are certain that your strings have no characters in them which might be interpreted as HTML control characters, you get better performance if you set escapeHTML to false. Is there any noticeable performance penalty if one sets escapeHTML to true? thanks, mai On Jul 11, 2011, at 6:43 PM, Mike Schrag wrote: > You have to be mindful of ever rendering any tainted strings ...
