session-variables

问题 I've been searching for long time of solving the limitation in asp file uploading as the case in my question File Upload: Fail to assign value into File, it still not answered by anybody. At this moment, can i know is there anybody here know how to use session to store an image for temporary, and thereafter retrieve it back to the stream and put it into the model ? 回答1: You could convert the image into a byte array then convert it to a base64 string and save that into the session.

问题 I have requirement where in I need to read message from a JMS Queue from inside a Component. But during this process the session variables associated with the message are missing. But the session variables are available when the same message is read from JMS:inbound-endpoint instead of from inside a component. Here are my sample flows. Main flow sets a session-variable into MuleMessage and posts it onto a JMS:outbound-endpoint <flow name="main-flow" > <some inbound> ... < Some processing >

问题 I am just learning grails and have a problem with an app that works fine when I run it in Netbeans but shows strange behavior when deployed to Tomcat 7.0.22 on a Centos 5.4 server. I am using the proxy_ajp to make the app available with apache. The problem seems to be with the session not being maintained after a redirect so that I lose the login information causing the app to try to login again. My proxy_ajp settings are <Location /PreyerBooks > ProxyPass ajp://localhost:8011/PreyerBooks

问题 I'm having a problem to make my facebook app working on Safari. The issue is related to the PHP session variables. I am aware that Safari has a problem dealing with cross domain sessions (inside an iframe) and i found around 2 types of solutions: Setting the p3p header: i've tried many p3p header found around but no one of them worked [for example: header('P3P: CP="NOI ADM DEV COM NAV OUR STP"'); ]. Sending a post to the iframe, using javascript. This creates interaction and sessions should

问题 Preface : this is a "development" from an earlier question of mine, whose answers didn't solve my problem in the end. But through trying all the suggestions and also trying other stuff, I discovered that the real problem is something else, so I rephrase my question here I have a login page/system which has worked correctly for years, leaving the user logged in until he/she either closes the browser window or logs out manually. But lately after only a few minutes of inactivity the session

问题 Is it "better" (more efficient, faster, more secure, etc) to (A) cache data that is used on every page load in the $_SESSION array (but still querying a table for a flag to reload the data fresh), or (B) to load it from the database each time? I'm using the cache method (A), but I'm worried that with hundreds of users, memory could become an issue? It's just simple data, like firstname, lastname, birthday, etc. With either method, there's still a query being run. Thoughts? 回答1: If your data

问题 Here's what I would like to do: \set values foo,bar,baz DO $$ DECLARE value TEXT; values TEXT[] := string_to_array(:'values', ','); BEGIN FOREACH value IN ARRAY values LOOP raise notice 'v: %', value; END LOOP; END $$ LANGUAGE plpgsql; Which results in the following error: ERROR: syntax error at or near ":" SELECT string_to_array(:'values', ',') INTO values... ^ Here's the solution I have currently, but it feels hacky: \set values foo,bar,baz PREPARE get_values AS SELECT string_to_array(:

问题 In my ASP.NET MVC app, when I authenticate the user with OAuthWebSecurity, Facebook sends back an ExtraData which contains the access token. Initially I thought of storing this in the database, but it says in the FB docs: You should also remove the stored access token. ...when logging the user out. So the token should be handled as a session variable, but in ASP.NET MVC I don't have session variables (or there are ways, but it's not a good pattern). What is the best way to store the FB user

问题 I'm trying to check the progress of files uploaded. I'm using the Kohana framework which has a Session class, but for the upload progress I'm using native PHP sessions. I'm calling session_start() in Kohana's bootstrap.php, which means session_start() will be called on every page request. After the upload form is submitted, I wait 1 second and then begin calling a PHP file to check the upload progress using jQuery $.ajax() . The problem is that $_SESSION[$key] ($key contains the key for the
