Escaping Unsafe Characters

no specific attributes are identified in the URL, all attributes are returned in the search.

2. Escaping Unsafe Characters

Any unsafe characters in the URL need to be escaped, or substituted with a special sequence of characters.

For example, a space is an unsafe character that must be represented as %20 within the URL. Thus, the distinguished name o=example.com corporation must be encoded as o=example.com%20corporation.

The following table lists the characters that are considered unsafe within URLs and provides the associated escape characters to use in place of the unsafe character:
