A computer-implemented method, comprising: receiving an access request based on a short link; parsing the short link based on the access request to obtain a long link that matches the short link; checking, based on a predefined long link regular expression, the long link obtained through parsing, wherein the long link regular expression is sent by a configuration server; and redirecting the access request to the long link obtained through parsing after the check succeeds by determining a domain name corresponding to the long link; collecting statistics about access traffic of the domain name within a specified time period; determining, based on the access traffic and a traffic limiting threshold preset for the domain name, whether the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold; in response to determining that the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold, redirecting the access request to a predetermined traffic limiting page; and in response to determining that the access traffic of the domain name corresponding to the long link does not exceed the traffic limiting threshold, redirecting the access request to the long link obtained through parsing. receiving an access request based on a short link; parsing the short link based on the access request to obtain a long link that matches the short link; checking, based on a predefined long link regular expression, the long link obtained through parsing, wherein the long link regular expression is sent by a configuration server; and redirecting the access request to the long link obtained through parsing after the check succeeds by determining a domain name corresponding to the long link; collecting statistics about access traffic of the domain name within a specified time period; determining, based on the access traffic and a traffic limiting threshold preset for the domain name, whether the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold; in response to determining that the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold, redirecting the access request to a predetermined traffic limiting page; and in response to determining that the access traffic of the domain name corresponding to the long link does not exceed the traffic limiting threshold, redirecting the access request to the long link obtained through parsing. determining a domain name corresponding to the long link; collecting statistics about access traffic of the domain name within a specified time period; determining, based on the access traffic and a traffic limiting threshold preset for the domain name, whether the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold; in response to determining that the access traffic of the domain name corresponding to the long link exceeds the traffic limiting threshold, redirecting the access request to a predetermined traffic limiting page; and in response to determining that the access traffic of the domain name corresponding to the long link does not exceed the traffic limiting threshold, redirecting the access request to the long link obtained through parsing.
