pki http

Before you configure a device to use HTTP to download a CA certificate, local certificate, or CRL, ensure that the CFcard or Hda1 of the device has enough space to accommodate the CA certificate, local certificate, or CRL.

An administrator cannot enter command lines that include a question mark (?). Keyword esc supports the entering of URLs that include the question mark (?) in the ASCII code, and 3f is the hexadecimal ASCII code for the question mark (?). Therefore, the entered URL must be in \x3f format. For example, the URL that an administrator needs to enter is http://www.example.com\x3fpage1, instead of http://www.example.com?page1. If the administrator wants to configure http://www.example.com?page1\x3f that includes both a question mark (?) and \x3f, the administrator should add an escape character (\) to \x3f and enter http://www.example.com\x3fpage1\\x3f.
