MIME-160 — Error when looking MIME type in database
In HTTP protocol, server indicates to client the MIME type of response data using Content-Type header. If the header is missing, proxy tries to guess the type from the suffix of the request URI. During initialization, the proxy reads a file which defines mapping from suffixes to MIME types. Content of the file is stored internally in the form of db(3) database. Later, MIME types are looked up in the database according to file extensions of HTTP requests. This message indicates that an error occurred during lookup in the database.
