HTTP:persist(save_tbl)

Saves the entry to the stick table.

Syntax

HTTP:persist(t);

Arguments

Name	Description
t	A table specifies the operation, hash value, and server_name.

Events

Applicable in the following events:

• PERSISTENCE

• POST_PERSIST

• HTTP_REQUEST (supported since version 7.2.x)

Example

when PERSISTENCE{
    cip = HTTP:client_addr()
    hash_str_cip = sha512_hex(cip)

    debug("-----save_tbl-----\n")
    t={}
    t["operation"] = "save_tbl"
    t["hash_value"] = hash_str_cip
    t["srv_name"] = "pool1-2"
    ret = HTTP:persist(t)
    if ret then
	    debug("hash save table success\n");
	else
	    debug("save table failed\n");
	end

	t={};
	t["operation"] = "save_tbl";
	t["hash_value"] = "246810";
	t["srv_name"] = "pool1-3";
	ret = HTTP: persist(t);
	if ret then
	    debug("===server add success\n");
    else
        debug("===server add fail\n");
    end
}
Output:
true: success, false: failed

Note:

Due to limitations in the stick table, it only supports 16 characters in the hash value. Otherwise, we will hash it to obtain 16 bytes as index.

Supported Version

FortiADC version 5.4.x and later. In 7.2.x, function extended to HTTP_REQUEST events.
