A pipeline connection device includes a first connecting member, a second connecting member and a sealing member. The first connecting member includes a first channel and an abutting portion. The second connecting member includes a second channel and a first groove portion. The first groove portion includes a first side wall and a first receiving groove to receive the sealing member. At least part of the abutting portion is received in the first receiving groove and abuts against the sealing element. A first gap not greater than 0.3 mm is provided between the abutting portion and the first side wall; or the first connecting member and the second connecting member include at most two annular friction surfaces. As a result, mutual jamming of the first connecting member and the second connecting member can be avoided. Besides, a pipeline adapting assembly having the pipeline connection device is disclosed.

The present disclosure discloses a method, a web server and a web browser of providing information. The method of providing information includes: in response to receiving a webpage access request of a user, obtaining, by a web server, attribute information of second product information that matches with first product information corresponding to a webpage which the user requests to browse; finding second product information which satisfies the attribute information; and sending the found second product information to a web browser used by the user in order for the webpage browser to include the received second product information in the webpage for provision to the user. The technical scheme of the present disclosure solves the problem of repeatedly performing actions (such as searching, clicking, browsing, etc.) by a user in an electronic commerce website and thereby wasting a relatively large amount of processing resources of the electronic commerce website under existing technologies.

Method, web server and web browser of providing information

Embodiments of the present application relate to a method of controlling float-out messages, a system for controlling float-out messages, an instant messaging client for controlling float-out messages, and a computer program product for controlling float-out messages. A method of controlling float-out messages is provided. The method includes in the event that there is a float-out message that is ready to be sent to a recipient, determining a current status of the recipient of the float-out message, in the event that the current status of the recipient is online, determining whether the float-out message should be sent to the recipient, including determining whether an identifier value of the recipient has reached a threshold value, the identifier value being used to indicate whether the recipient is deemed to be currently in a state of fatigue or a level of fatigue the recipient is deemed to be in, in the event that the identifier value has not reached the threshold value, pushing the float-out message to the recipient to be made available for float out by the recipient, and updating the identifier value.
