HOW MANY WAYS CAN WE GET THE VALUE OF CURRENT SESSION ID?
session_id() returns the session id for the current session.
How can you get the session after the user logs out in PHP?
Depends what you mean with that. If the user logs out, the session gets destroyed, and with it the session ID. You'd need to grab the session ID before the user logs out.
What is session in aspnet?
session is a server variable. it works like the ordinary variable but it is stored on the server
WHAT is the difference between session and cookie in php?
The session is stored on the web server. The cookies is stored in a little file on users machine. This means that the session is (relatively) secure, whereas the cookie can be edited by the end user.
What is a session What are the different ways of session tracking in servlet programming?
In servlet programming, a session is a way to maintain state between multiple requests from the same client. There are several ways to track sessions in servlet programming, including cookies, URL rewriting, and hidden form fields. Cookies are the most commonly used method, where a unique identifier is stored on the client's browser to associate subsequent requests with the same session. URL rewriting involves appending session IDs to URLs, while hidden form fields store session IDs in HTML forms.
What is session in java?
Why do we need a Session?When one page needs to share information with another, the scope of the data broadens beyond processing a single request. This is because, when a response gets committed, all the data that was held in the request that generated that response is destroyed. So, if you want that data in another page, you will be looking at a blank request object with no data in it. When such a need arises, you must send the data from one page to the server and from the server to the next requested page, whether it be the same page or another page altogether. There are several ways to share state information between requests. However, the primary or the easiest way is to use sessions.How Do Sessions Work?The container generates a session ID. When you create a session, the server saves the session ID on the client's machine as a cookie. If cookies are turned off then it appends the ID in the URL. On the server, whatever you add to the session object gets placed in server memory-very resource intensive. The server associates that object in memory with the session ID. When the user sends a new request, the session ID is sent too. The server can then match the objects in its memory with that session ID. This is how we maintain client state.
What is a php session?
A PHP session is a concept where specific variables (and their respective values) are carried throughout a user's viewing of a PHP-driven website. These sessions can be initialized and continued using the session_start() function. The session values are stored in the $_SESSION global variable. For more information, see the php.net documentation of session functions.
What is inproc in detail?
InProc Session StateInProc state is considerably faster than either the state server or SQL Server session storage techniques. SQL Server and state server attribute their slowness to serialization/deserialization that happens while reading in/storing out the Session data from the SQL/State server. . However storing the session state InProc has its own share of limitations. Some of these are- With each app domain restart Session state is lost- Process restart will result in loss of Session state data- If considerable amount of data are stored in Session state, memory consumption for the process may increase to the point of experiencing issues due to high memory. Therefore, the amount of data being stored in Session state and the time frame during which these data need to be stored should be limited as much as possible.- In case one wants to implement InProc Session state in a web farm scenario ensure we have sticky sessions enabled for the web farm as it involves storing of the session data among processes hosted on multiple servers.
How do you encode URLs?
Let's We understand ,how to deal with the "String encodeURL(String URL)" method in "HttpResponse" Interface , We can call this method by taking response reference variable , So here encode method is a method which will search the session object and gets the session id from it and finally it will append or add this session id to the URL address which we are passing to this method at the time of calling it (i,e response.encodeURL("/anyurladdress") ). As the return type of this method is a String ,so it is going to return a String value (i,e "anyurladress + session ID" ). Once we receive this "URL+sessionID" we can use it , when we are sending the second request from the same client . So server or container can recognize whether the client is already an existing one or the new one based on the session ID which we are sending along with the URL address.

What is the Difference between session and viewstate in asp?
1) Viewstate is particular to a control/page whereas session is for the whole application. You can access the session data stored in page A in page B but viewstate does not behave so. 2) ViewState is maintained at client side whereas session is maintained at server side 3) Since viewstate is maintained at client, it does not have a concept of expiry but session will expire after the stipulated time 4) You can enable/disable view state for specific controls but you can't do that for session. abhishek patel, mobile number:9558551202
What does servlet session API means?
The Servlet Session API refers to the documentation on the list of methods available in the HttpSession class that is used for Session ManagementThe HttpSession object is very powerful and has many features. Before we dig deep into the world of Sessions, let us take a look at the important methods they have so that we can use them effectively.• getAttribute(java.lang.String name) - Returns an Object associated with that name that was stored in the session object.• getAttributeNames() - Returns an Enumeration object that lists the names of the objects stored in the session object.• getCreationTime() - Returns a long containing the date stamp of creation.• getId() - Returns the id of the session as a String representing the unique identifier assigned to this session.• getLastAccessedTime() - Returns a long containing the date stamp of the last time the session was accessed.• getMaxInactiveInterval() - Returns an integer representing the maximum time interval, in seconds, that the servlet container will keep this session open between client accesses.• invalidate() - This destroys a session. It can't be referenced after this method has been called.• isNew() - This tells you whether the client knows about the session. In other words, the has session been created by the server, but the client hasn't acknowledged receiving the session ID yet.• removeAttribute(java.lang.String name) - This removes an attribute. It deletes it from the session object.• setAttribute(java.lang.String name, java.lang.Object value) - You use this method to add objects to a session.• setMaxInactiveInterval(int interval) - Specifies the time, in seconds, between client requests before the servlet container will invalidate this session.• getValue(java.lang.String name) - Returns an Object associated with that name that was stored in the session object. As of Version 2.2, this method is replaced by getAttribute(). The getAttribute() method will be on the exam, not this one, but it is here for completeness.• getValueNames() - Returns a String array with a list of names associated with the objects added to a given session. As of Version 2.2, this method is replaced by getAttributeNames(). The getAttributeNames() method will be on the exam, not this one, but it is here for completeness.• putValue(java.lang.String name, java.lang.Object value) - You use this method to add objects to a session. This has been deprecated. As of Version 2.2, this method is replaced by setAttribute(java.lang.String, java.lang.Object). The setAttribute() method will be on the exam, not this one, but it is here for completeness.• removeValue(java.lang.String name) - This removes a value, but retains an attribute name in the session. The name is valid but the object is null. This has been deprecated. As of Version 2.2, this method is replaced by removeAttribute(). The removeAttribute() method will be on the exam, not this one, but it is here for completeness.
