    Can we apply NE flag to RewriteCond? Applying this resulting into failure to load JBoss

    Gurushant Birajdar Newbie



      I am trying to use JBoss Rewrite to restrict some URl to be accessed by any user. For this I have used following code


           RewriteCond %{QUERY_STRING} .*/abc.html.* [NC,NE]

           RewriteRuke ^/app(.*) - [F]


      Here, I want to restrict access to all such URL's which contains string "/abc.html". The above rule is working fine for all possible URL's except when used encoded characters like %6D for 'm'.

      For example, If I hit URl like " http://myserver/app?service=access&path=/xyz-0-1-2/abc.ht%6dl" in browser, then Rewrite valve should return me 403 response.

      But, currently when I apply [NE] flag in front of RewriteCond, JBoss fails to get load successfully. I could find the following in my Jboss log,


           WARN  [org.apache.tomcat.util.http.Parameters] Parameters: Character decoding failed. Parameter skipped.

           java.io.CharConversionException: isHexDigit

             at org.apache.tomcat.util.buf.UDecoder.convert(UDecoder.java:88)

             at org.apache.tomcat.util.buf.UDecoder.convert(UDecoder.java:49)


      I didn't get any information about the reason behind Failure in Jboss load, but when I remove [NE] flag, JBoss loads successfully.

      Is anybody have any idea about this issue or is there something went wrong in my RewriteRule.?
