Is there a way to use JSP to create a file tail like Linux's "tail -f" and cache the results? That is, can I read the last X items, cache, and then read again if I get a request that exceeds some timeout?

I'm trying to build a login system with ajax and php. I use a log-view where I then save the data in ajax which brings into my doLogin.php (php file). My problem is that php file should never be any ajax data for when I build it into a class and a function
VIEW:
public function DoLoginBox() {
//inloggning form-tagg...
return '<p> </p>
<div id="content">
<h1>Login Form</h1>
<form id="form1" name="form1" action="Handler/doLogin.php" method="post">
<p>
<label for="username">Username: </label>
<input type="text" name="username" id="username" />
</p>
<p>
<label for="password">Password: </label>
<input type="password" name="password" id="password" />
</p>
<p>
<input type="submit" id="login" name="login" />
</p>
</form>
<div id="message"></div>
</div>';
}
AJAX:
<script type="text/javascript">
$(document).ready(function() {
$("#login").click(function() {
var action = $("#form1").attr('action');
var form_data = {
username: $("#username").val(),
password: $("#password").val(),
is_ajax: 1
};
$.ajax({
type: "POST",
url: action,
data: form_data,
success: function(response)
{
if(response == 'success')
$("#form1").slideUp('slow', function() {
$("#message").html("<p class='success'>You have logged in successfully!</p>");
});
else
$("#message").html("<p class='error'>Invalid username and/or password.</p>");
}
});
return false;
});
});
</script
PHP:
<?php
require_once ("UserHandler.php");

public function Login (){
$is_ajax = !empty($_REQUEST['is_ajax']);
if(isset($is_ajax) && $is_ajax)
{
$username = $_REQUEST['username'];
$password = $_REQUEST['password'];

$UserHandler -> controllDB($username,$password);

{
echo "success";
}
}
}
}
` $DoLogingHandler = new DoLogingHandler();

Is there any way to programmatically determine if an .xls contains macros, without actually opening it in Excel?
Also are there any methods to examine which certificate (including timestamp cert) these macros are signed with? Again without using Excel.
I'm wondering in particular if there are any strings that always show up in the raw data of an Excel file when macros are present.
Hi!
I was wondering if it was possible to edit an xml on the server side from a web based flex application.
When you use XML files in a Flex application and then compile it to upload it in the server, Flex Buidler generates a swf file with the xml data embedded. How should I do to have access to those XML files??
Thanks for your answers.
Regards.

I am trying to read an ini file that has the following format:
SETTING=VALUE
SETTING2=VALUE2
I currently have the following code:
string cache = sr.ReadToEnd();
string[] splitCache = cache.Split(new string[] {"\n", "\r\n"}, StringSplitOptions.RemoveEmptyEntries);
Which gives me a list of settings, however, what I would like to do is read this into a dictionary. My question is, is there a way to do this without iterating through the entire array and manually populating the dictionary?
I'm trying to find something like this: http://coffeescripter.com/code/ad-gallery/ that is controlled by an xml file that can simply contain the image location, thumbnail location and the text for title/description. Has to be pure jquery or javascript though - no flash based stuff.
I've found loads of great components but can't find one that is controlled by XML. Anyone happen to have seen one around anywhere please?
