 +
 +==== $http_req_id ====
 +
 +The $http_req_id read-only variable can be used in REQUEST_ROUTE to retrive the unique identifier for a query after sending it or in the HTTP callback route to retrive the id of the query the reply belongs to. Useful mainly in non-transactional context.
 +
 +==== $http_req(key) ====
 +
 +The $http_req(key) write-only variable can be used to set custom parameters before sending a HTTP query.
 +
 +**key** can be one of:
 +  * all: if set to $null, resets all the parameters to their default value (the ones defined in modparam)
 +  * hdr: sets/modifies/removes a HTTP header. N.B.: setting this variable multiple times will add several headers to the query.
 +  * body: sets/modifies/removes the request body
 +  * method: sets the HTTP method: either "GET", "POST", "PUT" or "DELETE" (these are the supported methods). (Note: if the method is not set, curl will use GET, or POST if a body is specified)
 +  * timeout: sets the HTTP timeout. (Note, this timeout should be normally less than tm.fr_timer timeout, because transaction timeout has a higher priority over HTTP timeout)
 +  * tls_client_cert: sets the client certificate to use
 +  * tls_client_key: sets the client certificate key to use
 +  * tls_ca_path: sets the CA certificate path to use
 +  * authmethod: Sets the preferred authentication mode for HTTP/HTTPS requests. The value is a bitmap and multiple methods can be used. Note that in this case, the CURL library will make an extra request to discover server-supported authentication methods. You may want to use a specific value. Valid values are:
 +      * 1 - BASIC authentication
 +      * 2 - HTTP Digest authentication
 +      * 4 - GSS-Negotiate authentication
 +      * 8 - NTLM authentication
 +      * 16 - HTTP Digest with IE flavour.
 +      * (Default value is 3 - BASIC and Digest authentication.)
 +  * username: sets the username to use for authenticated requests
 +  * password: sets the password to use for authenticated requests
 +  * suspend: if set to 0 it doesn't suspend the current transaction before performing the query
 +  * tcp_keepalive: enable TCP keepalive
 +  * tcp_ka_idle: set TCP keepalive idle time wait
 +  * tcp_ka_interval: set TCP keepalive interval
 +
 +==== Other read-only variables ====
 +
 +The following read-only pseudo variables can only be used in the callback routes executed by http_async_query()
 +
 +=== $http_ok ===
 +1 if cURL executed the request successfully, 0 otherwise (check $http_err for details).
 +
 +=== $http_err ===

 +
 +=== $http_mb and $http_ml ===
 +HTTP response buffer (including headers) and length.

 +  * type[n] - returns the type of the nth element in the array. type - returns array type. 
 + 
 +  * value[n] - returns value of the nth element. value - returns null for an array. You need to get each element by index. 
 + 
 +In case one of the members of the array is also an array (for example calling SMEMBERS in a MULTI/EXEC transaction), the members of the array can be accessed by adding any of the above keys, after a value[n] key. The first value[n] references the element in the first array, while the next key references an element of the referenced array. 
 + 
 +Example: 
 + 
 +<code> 
 +redis_cmd("srvN", "GET foo", "r"); 
 +xlog("===== result type: $redis(r=>type) * value: $redis(r=>value)\n"); 
 +</code> 
 + 
 +==== $redisd(key) ==== 
 + 
 +Return the corresponding value for various defines from hiredis library. 
 + 
 +The key can be: 
 + 
 +  * rpl_str - return REDIS_REPLY_STRING 
 +  * rpl_arr - return REDIS_REPLY_ARRAY 
 +  * rpl_int - return REDIS_REPLY_INTEGER 
 +  * rpl_nil - return REDIS_REPLY_NIL 
 +  * rpl_sts - return REDIS_REPLY_STATUS 
 +  * rpl_err - return REDIS_REPLY_ERROR 
 + 
 +$redisd(rpl_XYZ) can be compared with $redis(r=>type). 
 + 
 +Example: 
 + 
 +<code> 
 +redis_cmd("srvN", "GET foo", "r"); 
 +if ($redis(r=>type) == $redisd(rpl_int)) {
