The following HTTP headers are supported:
• Content-Length (nonzero value required for all POSTs)
• Connection (close value indicates that a request should not be persistent)
• WWW-Authenticate (sent to the client when credentials are required and
missing)
• Authorization (sent from the client to specify basic credentials in base 64
encoding)
For example, when an XML error occurs, th
e HTTP response contains a 200
return code. The portion of the original XML document with the error is returned
with an error element that contains the error type and description.
The following is a typical example of an XML error response:
<response_xml>
<config_command>
<command>
interface vlan 20
no shut
description xyz
exit
</command>
<status code = ‘200’ text=’XML_CMD_FAILURE’>
<error_command> description xyz </error_command>
<error_message> unrecognized element - description </error_message>
</status>
</config_command>
</response_xml>
