Description

This function examines the parameters in the container to find a match for the specified key, which may contain percent escapes. The comparison is performed as if all escaped characters were decoded first. The search starts prior to before and proceeds backwards until either the key is found or the beginning of the range is reached, in which case end() is returned.

Example

url_view u( "?First=John&Last=Doe" );

assert( u.encoded_params().find_last( "last" ) != u.encoded_params().find_last( "last", ignore_case ) );

Complexity

Linear in this->buffer().size().
