An information sharing method for a first client, comprising: sending (step 101), by the first client, a uniform resource locator, URL, of a to-be-shared web page to a reverse proxy server by using a communication web page, so that the reverse proxy server maps the URL of the to-be-shared web page and a URL of the communication web page to a sharing URL, that is, the reverse proxy server maps the communication web page and the to-be-shared web page onto a same virtual website, wherein the sharing URL comprises the URL of the to-be-shared web page and the URL of the communication web page; receiving (step 102), by the first client, the sharing URL sent by the reverse proxy server; acquiring (step 103), by the first client, a first to-be-shared web page according to the sharing URL, wherein the first to-be-shared web page is generated according to user background information and comprises the user background information of the first client, the user background information comprises at least one of historical browsing data stored on the Internet and local historical browsing data stored in the first client, and data acquired by a user by logging in to a website by using user permission information; sending (step 104), by the first client, the sharing URL to a second client, so that the second client acquires a second to-be-shared web page according to the sharing URL so that the sharing URL of the first to-be-shared web page is the same as a sharing URL of the second to-be-shared web page, both of which are the sharing URL of the to-be-shared web page, wherein the second to-be-shared web page does not comprise the user background information of the first client; and sending (step 105), by the first client, a document object model, DOM, of the first client to the second client, wherein the DOM of the first client is corresponding to the first to-be-shared web page, so that the second client modifies a DOM of the second client according to the DOM of the first client, and generates the first to-be-shared web page according to a modified DOM of the second client and the second to-be-shared web page. sending (step 101), by the first client, a uniform resource locator, URL, of a to-be-shared web page to a reverse proxy server by using a communication web page, so that the reverse proxy server maps the URL of the to-be-shared web page and a URL of the communication web page to a sharing URL, that is, the reverse proxy server maps the communication web page and the to-be-shared web page onto a same virtual website, wherein the sharing URL comprises the URL of the to-be-shared web page and the URL of the communication web page; receiving (step 102), by the first client, the sharing URL sent by the reverse proxy server; acquiring (step 103), by the first client, a first to-be-shared web page according to the sharing URL, wherein the first to-be-shared web page is generated according to user background information and comprises the user background information of the first client, the user background information comprises at least one of historical browsing data stored on the Internet and local historical browsing data stored in the first client, and data acquired by a user by logging in to a website by using user permission information; sending (step 104), by the first client, the sharing URL to a second client, so that the second client acquires a second to-be-shared web page according to the sharing URL so that the sharing URL of the first to-be-shared web page is the same as a sharing URL of the second to-be-shared web page, both of which are the sharing URL of the to-be-shared web page, wherein the second to-be-shared web page does not comprise the user background information of the first client; and sending (step 105), by the first client, a document object model, DOM, of the first client to the second client, wherein the DOM of the first client is corresponding to the first to-be-shared web page, so that the second client modifies a DOM of the second client according to the DOM of the first client, and generates the first to-be-shared web page according to a modified DOM of the second client and the second to-be-shared web page.
