Package thredds.servlet.filter

Class RequestQueryFilter

java.lang.Object

thredds.servlet.filter.RequestQueryFilter

All Implemented Interfaces:

jakarta.servlet.Filter

public class RequestQueryFilter
extends Object
implements jakarta.servlet.Filter

Reject any request with an invalid query string.

The query string is considered valid if, after decoding, it is a single-line string. For more details, see StringValidateEncodeUtils.validSingleLineString(String) validSingleLineString()}.

Note: Currently also rejecting strings that contain any less than ("<"), greater than (">"), or backslash ("\") characters. [May loosen this restriction later.]

Note: HttpServletRequest.getQueryString()) is not decoded by default so we run it through URLDecoder.decode().

Since:

3.16.47
