HTTP

This timeout is counted as the amount of time when the client did not send a complete request HTTP header to the FortiADC after the client connected to the FortiADC. If this timeout expires, FortiADC will send a 408 message to client and close the connection to the client.

This timeout is counted as the amount of time when the server did not send a complete response HTTP header to the FortiADC after the FortiADC sent a request to server. If this timeout expires, FortiADC will close the server side connection and send a 503 message to the client and close the connection to the client.

This timeout is counted as the amount of time during which FortiADC tried to connect to the server with TCP SYN. After this timeout, if TCP connection is not established, FortiADC will drop this current connection to server and respond with a 503 message to client side and close the connection to the client.

This timeout is counted as the amount of time during which the request is queued in the dispatched queue. When the request cannot be dispatched to a server by a load balance method (for example, the server's connection limited is reached), it will be put into a queue. If this timeout expires, the request in the queue will be dropped and FortiADC will respond with a 503 message to client side and close the connection to the client.

This timeout is counted as the amount of time it took FortiADC to send a response body data (not including the header); the time is counted starting from when the body is transferred. If this timeout expires, FortiADC will close the connection of both side.

This timeout is counted as the amount of time the client did not send a complete request (including both HTTP header and request body) to FortiADC after the client connected to FortiADC. If this timeout expires, FortiADC will send a 408 message to client and close the connection to the client.

This timeout is counted as the time FortiADC can wait for a new request after the previous transaction is completed. This is an idle timeout if the client does not send anything in this period. If this timeout expires, FortiADC will close the connection to the client.

Use the original client IP address as the source address when connecting to the real server.

Append the client IP address found in IP layer packets to the HTTP header that you have specified in the X-Forwarded-For Header setting. If there is no existing X-Forwarded-For header, the system creates it.

If you only enable http-x-forwarded-for and do not configure http-x-forwarded-for-header, the default is to add such a header: X-Forwarded-For: <client's ip>

Specify the HTTP header to which to write the client IP address. Typically, this is the X-Forwarded-For header, but it is customizable because you might support traffic that uses different headers for this. Examples: Forwarded-For, Real-IP, or True-IP.

If http-x-forwarded-for-header <string> is configured, the added header is: <string>: <client's ip>,

Enable to apply the FortiGuard IP reputation service. See Managing IP Reputation policy settings.

Type a URL including the FQDN/IP and path, if any, to which a client will be redirected if the request violates the IP reputation policy.

• Server Close—Close the connection to the real server after each HTTP transaction.
• Once Only— An HTTP transaction can consist of multiple HTTP requests (separate requests for an HTML page and the images contained therein, for example). To improve performance, the "once only" flag instructs the FortiADC to evaluate only the first set of headers in a connection. Subsequent requests belonging to the connection are not load balanced, but sent to the same server as the first request.
• Keep Alive—Do not close the connection to the real server after each HTTP transaction. Instead, keep the connection between FortiADC and the real server open until the client-side connection is closed. This option is required for applications like Microsoft SharePoint.

Adjust the value of the HTTP/HTTPS VS's connection buffer size.

• For every session, there are two connection buffers.
• The default size is 8030, it is not recommended that you edit it. It's hidden in the Advance tab, and when you edit it you will get a warning message.
• Tuning this option is dangerous because it may lead to concurrent session number reduction or other unpredictable problems.

Adjust the max header number that HTTP/HTTPS VS can process for every request or response. If a request or response has a header over this limit, it will be dropped, and return error message 400.

• The default value is 100, it's not recommended that you edit it. It is hidden in the Advance tab, and when you edit it you will get a warning message.
• Tuning this option is dangerous and may lead to concurrent session number reduction or other unpredictable problems.

EXPLICIT_HTTP

This timeout is counted as the amount of time when the client did not send a complete request HTTP header to the FortiADC after the client connected to the FortiADC. If this timeout expires, FortiADC will send a 408 message to client and close the connection to the client.

This timeout is counted as the amount of time when the server did not send a complete response HTTP header to the FortiADC after the FortiADC sent a request to server. If this timeout expires, FortiADC will close the server side connection and send a 503 message to the client and close the connection to the client.

This timeout is counted as the amount of time during which FortiADC tried to connect to the server with TCP SYN. After this timeout, if TCP connection is not established, FortiADC will drop this current connection to server and respond with a 503 message to client side and close the connection to the client.

This timeout is counted as the amount of time during which the request is queued in the dispatched queue. When the request cannot be dispatched to a server by a load balance method (for example, the server's connection limited is reached), it will be put into a queue. If this timeout expires, the request in the queue will be dropped and FortiADC will respond with a 503 message to client side and close the connection to the client.

This timeout is counted as the amount of time it took FortiADC to send a response body data (not including the header); the time is counted starting from when the body is transferred. If this timeout expires, FortiADC will close the connection of both side.

This timeout is counted as the amount of time the client did not send a complete request (including both HTTP header and request body) to FortiADC after the client connected to FortiADC. If this timeout expires, FortiADC will send a 408 message to client and close the connection to the client.

This timeout is counted as the time FortiADC can wait for a new request after the previous transaction is completed. This is an idle timeout if the client does not send anything in this period. If this timeout expires, FortiADC will close the connection to the client.

Use the original client IP address as the source address when connecting to the real server.

Enable this option to append the client IP address found in IP layer packets to the HTTP header, for example, X-forwarded-for: 192.168.161.100.

The default header name is X-forwarded-for. If you prefer a different name, use X-Forwarded-For Header to define a custom name.

Specify a custom name for the HTTP header which carries the client IP address. Do not include the 'X-' prefix. Examples: Forwarded-For, Real-IP, or True-IP.

Adjust the value of the HTTP/HTTPS VS's connection buffer size.

• For every session, there are two connection buffers.
• The default size is 8030, it is not recommended that you edit it. It's hidden in the Advance tab, and when you edit it you will get a warning message.
• Tuning this option is dangerous because it may lead to concurrent session number reduction or other unpredictable problems.
