WEB READNEXT HTTPHEADER

Description

WEB READNEXT HTTPHEADER retrieves the next HTTP header in the list of headers. The SESSTOKEN option is required if the HTTP header information is part of a response sent to CICS® as an HTTP client.

Options

HTTPHEADER(data-area)

specifies the buffer to contain the name of the HTTP header being extracted.

NAMELENGTH(data-area)

specifies the length of the buffer supplied on the HTTPHEADER option, as a fullword binary data area, and is set to the actual length of the data returned to the application. If the data exceeds the buffer length, a LENGERR condition is raised and the data is truncated.

SESSTOKEN(data-value)

For CICS as an HTTP client, this option is required. It specifies the session token, an 8-byte binary value that uniquely identifies a connection between CICS and a server. This value is returned by a WEB OPEN command for CICS as an HTTP client. Session tokens explains the use of the session token.

VALUE(data-area)

specifies the buffer to contain the value of the HTTP header being extracted.

VALUELENGTH(data-area)

specifies the length of the buffer supplied on the VALUE option, as a fullword binary data area, and is set to the actual length of the data returned to the application. If the data exceeds the buffer length, a LENGERR condition is raised and the data is truncated.
