  • How does IIS persist a user's identity from page to page?

    - by Rising Star
    Web pages are, by nature, state-less objects. When you click from page to page in an ASP.net application, each request for a page is treated as a brand-new request. We use things like cookies, session-variables, and query strings to maintain state from page to page. When you log in to an ASP.net web application using Windows Authentication, how does IIS persist your identity between pages?

  • How to do a Post/Redirect/Get using Sinatra?

    - by John Topley
    What's Sinatra's equivalent of Rails' redirect_to method? I need to follow a Post/Redirect/Get flow for a form submission whilst preserving the instance variables that are passed to my view. Does the redirect method preserve them? (I'm at work at the moment and don't have access to Sinatra to try for myself.)

  • Is content from AJAX call added to Django context variable

    - by John
    Hi, I am using the JQuery load function to load part of my page. Can I access the variables from that page in the page that loads it. e.g. Page A uses JQuery load function to load B Page B loads and sets a variable in context called pageB_var which holds a django object Page A can then access this variable by doing {{pageB_var}} since it was added to the context If not what is the best way of doing this? Thanks

  • PHP Array Not Working in Function

    - by lemonpole
    Hello all. I'm currently experimenting with arrays in PHP, and I created a fake environment where a team's information will be displayed. $t1 = array ( "basicInfo" => array ( "The Sineps", "December 25, 2010", "lemonpole" ), "overallRecord" => array (0, 0, 0, 0), "overallSeasons" => array ( 1 => array (14, 0, 0), 2 => array (9, 5, 2), 3 => array (12, 4, 0), 4 => array (3, 11, 2) ), "games" => array ( "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />" ), "seasonHistory" => array ( "Season I", "Season II", "Season III", "Season IV" ), "divisions" => array ( "Open", "Main", "Main", "Invite" ) ); // Displays the seasons the team has been in along // with the record of each season. function seasonHistory() { // Make array variable local-scope. global $t1; // Count the number of seasons. $numrows = count($t1["seasonHistory"]); // Loop through all the variables until // it reaches the last entry made and display // each item seperately. for($v = 0; $v <= $numrows; $v++) { // Echo each season. echo "<tr><td>{$t1["games"][$v]}</td>"; echo "<td>{$t1["seasonHistory"][$v]}</td>"; echo "<td>{$t1["divisions"][$v]}</td></tr>"; } } I have tested several possible problems out and after narrowing them down I have come down to one conclusion and that is my function is not connecting to the array for some reason. I don't know what else to do because I thought making the array global would fix that problem. What works: I can echo $t1["games"][0] on the page I need it to display and it gives me the content. I tried echo $t1["games"][0] INSIDE the function and then calling the function and it doesn't display anything.

  • How to return a const QString reference in case of failure?

    - by moala
    Hi, consider the following code: const QString& MyClass::getID(int index) const { if (i < myArraySize && myArray[i]) { return myArray[i]->id; // id is a QString } else { return my_global_empty_qstring; // is a global empty QString } } How can I avoid to have an empty QString without changing the return type of the method? (It seems that returning an empty QString allocated on the stack is a bad idea) Thanks.

  • Heap Behavior in C++

    - by wowus
    Is there anything wrong with the optimization of overloading the global operator new to round up all allocations to the next power of two? Theoretically, this would lower fragmentation at the cost of higher worst-case memory consumption, but does the OS already have redundant behavior with this technique, or does it do its best to conserve memory? Basically, given that memory usage isn't as much of an issue as performance, should I do this?

  • How to externalize web.xml servlet init-param? Spring DelegatingFilterProxy for Servlets?

    - by jnorris
    I have a 3rd-party servlet that I cannot modify. It accepts an init-param that I would like to externalize (from web.xml). I can externalize a servlet filter init-param using DelegatingFilterProxy. This effectively moves the servlet filter definition into Spring where there are much more powerful externalization tools (eg: PropertyPlaceholderConfigurer, environment variables, etc.) How can I do this for a servlet?

  • Session_End Alternatives

    - by grimus
    I have seen in some other questions that using Session_ End() in Global.asax.cs is not advised. This is because if you're not using the default Session handler, Session_End won't get called, correct? Is there any other cases where it won't get called? The big question is: If you can't depend on Session_End(), what do you do to determine when a session has closed?

  • Session vs singleton pattern

    - by chobo
    Hi, I have a web application where I would like to pull user settings from a database and store them for Global access. Would it make more sense to store the data in a Singleton, or a Session object? What's the difference between the two? Is it better to store the data as an object reference or break it up into value type objects (ints and strings)? Thanks!

  • Does OpenCL allow concurrent writes to same memory address?

    - by Wonko
    Is two (or more) different threads allowed to write to the same memory location in global space in OpenCL? The write is always changing a uchar from 0 to 1 so the outcome should be predictable, but I'm getting erratic results in my program, so I'm wondering if the reason can be that some of the writes fail. Could it help to declare the buffer write-only and copy it to a read-only buffer afterwards?

  • session variable values are not being passed between pages

    - by ravi nankani
    hi, i am a little new to php and although i have managed to pass values of session variables before this piece of code is leaving me puzzled <form action="team_reg2.php" method="post" name="form1" class="cent" id="form1"> Team Registration "; print "member$i"; print "\n"; print "\n"; print "Please enter only id\n"; } ? now this will pass via post to team_reg2.php echo " please note your team id is 1 "; echo " your team members are : "; for($i=1;$i<=$num;$i++) { $name='mem'.$i; echo "$_POST[$name]"; } } else { $str="select * from $query where ("; for($i=1;$i<=$num;$i++) { $name='mem'.$i; $text="p_id='$_POST[$name]'"; if($i==1) $str=$str.$text; else $str=$str.' or '.$text; } $str=$str.')'; $query2=$str; echo "$str"; // echo "$query2"; $que=mysql_query($query2,$con) or die(mysql_error()); $num=mysql_num_rows($que); if($num!=0) { while($result=mysql_fetch_array($que)) { echo "$result[p_id] is already registered in team $result[t_id]"; } //include("reg_team.html"); } else if($num==0) { //echo $query; $query2="select max(t_id) from $query"; $que=mysql_query($query2,$con) or die(mysql_error()); //echo "$que"; $result=mysql_fetch_array($que); $max=$result['max(t_id)']; $max++; $num=$_SESSION['max_team']; for($i=1;$i<=$num;$i++) { $name='mem'.$i; if($_POST[$name]!="") { $query2="insert into $query values($max,'$_POST[$name]')"; $que=mysql_query($query2,$con); } } echo " please note your team id is $max "; echo " your team members are : "; for($i=1;$i<=$num;$i++) { $name='mem'.$i; echo "$_POST[$name]"; } } } ? i have done session_start(); at the beginning of the page itself. The problem is that echoing $_SESSION variables in second file is not printing anything. someone please explain me whats going on. thank you

    - by DxCK
    Hi I writing a WCF Service that need transfer large files, so i using streaming, but from the other hand i need to do username specific initializations. The problem is that getting the username and perform initialization every time is very expensive.
