session-variables

问题 A neat feature which I found in CakePHP was the ability to set a flash message, say on some save script, then have that message displayed on the following page. Something like, Post updated , or Error - no file found. The way Cake does it is with this session object. I am trying to avoid sessions like the plague because of their odd requirements for scalability. Can I not just simply store the flash message in a cookie (client side) and then delete that cookie once it's displayed on the

问题 this is only happening in Chrome Has anyone ever experienced PHP sessions storing functional behavior into variables? I created the following script: <?php session_start(); $_SESSION['count'] = (isset($_SESSION['count'])) ? $_SESSION['count'] + 1 : 0; echo $_SESSION['count']; ?> You'd think this would echo 0, 1, 2, 3, etc. on each page load. However, I'm getting 1, 3, 5, 7, and so on. I found out that for some reason, $_SESSION['count'] acts as though its incrementing behavior has been stored

问题 I have a strange encounter when creating a GridView using SELECT..WHERE..<field> IN (value1, val2...) . In the "Configure datasource" tab, if i hard code the values SELECT .... WHERE field1 in ('AAA', 'BBB', 'CCC') , the system works well. However, if I define a new parameter and pass in a concatenated string of values using a variable; be it a @session, Control or querystring; e.g. SELECT ....

问题 I came across a weird behavior today w/ my web application. When I navigate from a page to another, I lose one particular session variable data.

Below code was used to track session variables System.IO.StreamWriter sw = new System.IO.StreamWriter(@"c:\test.txt", true); for (int i = 0; i < Session.Count; i++) { sw.WriteLine(Session.Keys[i]

问题 NOTE: I know the various reasons to avoid using the session, but this is a project I've inherited, so please skip that part of any replies :) Since it's a solved problem, I'm hoping someone can point to an ELMAH patch/branch/fork that includes logging session data rather than reinventing the wheel. One weird thing is an older post from Atif that says they're already logged: http://markmail.org/message/ncmdgwm5rmzewbwu commenter henningst mentioned adding in the session variables here: http:/

问题 I have a asp.net project with c# code behind. I have a static class called GlobalVariable where I store some information, like the currently selected product for example.

I would want to create (from the c# code) some kind of session variable used only from the c# code, but not only from the page, but from any
