sticky session

What ls-al/tmp see today is RWXRWXRWT is surprised what this t is, how is it not X or-? Search for the following discovery: This t represents the so-called sticky bit. Sticky bit: This bit can be understood as an anti-delete bit. Whether a file can be deleted by a user depends primarily on whether the group to which the file belongs has write access to the user. Without write permissions, all

Fixed of position attribute Fixed always uses the body as the object for positioning. It always locates elements based on the browser window and locates elements based on the left, right, top, and bottom attributes. After running on vscode The page can be rolled because the PX settings are large enough After dragging the scroll bar, as shown in figure We can find that the position of Layer 2 remains unchanged as the scroll bar slides down. This is the fixed attribute. If the position: fixed;

Python/socket programming of sticky bagSticky Bag:Only TCP has a urine packet phenomenon, UDP will never sticky packets.First you need to master a socket to send and receive messagesthe principleThe sender can be 1k,1k send data and the receiving end of the application can 2k,2k extract data, of course, it may be 3k or more K extract data, that is, the application is not visible, so the TCP protocol is the

When your Dodecode () method returns false, Cumulativeprotocoldecoder stops the call to the Dodecode () method, but at this point, if the data still has not been read, it will contain the remaining data Iobuffer The buffer is saved to iosession so that the next time the data arrives you can extract the merge from the iosession. If you find that this data is all read, empty the iobu

First, what is sticky bagNote: Only TCP has a sticky packet phenomenon, UDP will never stick packetsSticky bags do not necessarily occurIf this happens: 1. may have been glued on the client2. The client is not sticky and may be stuck on the service sideFirst you need to master the principle of a Socket transceiver messageThe data that the application sees is a wh

For example, we and the Client Convention data interaction format is a JSON-formatted string: {"Id": 1, "Name": "Golang", "message": "Message"} When the client sends the data to the server, if

Originally I intend to open a separate chapter, specifically to explain the sticky bag and broken bag, but I think this thing I am doing is a headache, but for others may not be so important, so write it here.So what is a sticky bag or a broken bag? Sticky pack: We know that the client writes the message to the server, the first thing to write to buffer,

When you assign a sgid to a directory, the user who creates the file in its directory must be a member of its directory's genus Group.2. When Sgid is in a directory, the owning group of the newly created file or directory within the directory automatically inherits the owning group of that directory3. When creating a

Imagine, however, what would happen if any ordinary user were able to delete temporary files that were used in the running of the system service?The sticky bit permission is set for this situation, and when the directory is set with the sticky bit permission, even if the user has write ac

In Linux, if you have write access to a directory, then we can create a delete file in this directory.Now we're going to create a directory where we can create files, but other users can't delete the file.A special permission is used here: sticky bitsThere are three special permissions in Linux, namely:SetUID = 4: Permissions set on the ownerSetGID = 2: Permissions set in the owning groupSticky bit = 1: Set in other people's position (denoted by T)Fir

encoding is based on the current system, if it is windows, then Res.stdout.read () read out is GBK encoded, at the receiving end needs to use GBK decoding, and can only read the results from the pipeline.2, sticky bag phenomenonOnly TCP has sticky packet phenomenon, TCP protocol is a flow-oriented protocol, which is prone to sticky packet problems. For example,

At present, the TCP/IP communication protocol and its standard socket application Development Programming Interface (API) are widely used in network transmission applications. The TCP/IP transport layer has two parallel protocols: TCP and UDP. Where TCP (Transport Control Protocol, Transmission Control Protocol) is connection-oriented, it provides high reliability services. UDP (User Datagram Protocol, Subscriber Datagram Protocol) is connectionless, providing efficient service. In practical eng

Rxbus, Eventbus because of the decoupling is too thorough, misuse, the project maintainability will be lower; some simple scenarios recommend using callbacks, subject instead of event bus. The actual use of the scene, if Rxbus,eventbus two, I prefer to use Eventbus, Rxjava focus on workflow, Eventbus focus on the event bus, clearer responsibilities For a while, a few months ago, I wrote a simple Rxbus article: Implement the event bus with Rxjava. In the real world, you will find that Rxbus still
