--- Comment #8 from Vincent Liautaud <vincent.liaut...@free.fr> --- Hi Remy, thank you for your reply and i understand the issue regrding the memory usage of this concurrent map. Anyway, as explained before we have been in a position where multiple requests exist at a time for a same session (which is explicitly explained to avoid in your documentation, as you noticed) because : 1-The documentation contained an example of filter : filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html| .*\.css|.*\.txt" This filter introduced a malicious space character before the .*\.css !!! For users (like me) who had copy and paste this filter in their configuration file, all css requests were not filtered (so Servlet + CSS generate concurrent requests for a same session => It seems you have corrected the documentation recently (So Thanks, problem fixed). 2-There had no debug trace in order to display all the requests that have not been filtered. This kind of trace would be very useful to identify some lack on the filter (to check that no file type extention have been forgotten on these filter).
