you can navigate to both like so<br />
www.mysite.com/Page1.aspx, www.mysite.com/Home.aspx</p>
<p>Page1 is now undergoing a lot changes so that it is going to end up looking a lot like Home except for some really small text changes. Also there are a number of emails in the wild with customers that link to Page1 and \ or Home </p>

<ol>
<li><p>Create One page( say newhome.aspx) which displays the correct text based on the URL of the link that people clicked on to get here </p></li>
<li><p>Let existing links go to this new page( and of course as per the above requirement the appropriate text would be displayed) </p></li>

Basically I feel I should explain why I am doing this.
I want users to be able to control when they get a notification, based off some data that one of their "channels" has saved.</p>
<p>For instance, a user only wants to get a notification when their collected data is bigger than 60. So I would get them to choose two fields:</p>
<p>First field input of their number (int or float)</p>
<p>Second field choises (equals, <, >, =<, =>)</p>
<p>The last thing in this if statement would be their data collected by their "channel".</p>
<p>I then want to be able to save their choice in a database, somehow, and then later act upon their choices.</p>

<p>Also instead of sliding can the effect be changed to actually moving up and down as the slide effect looks more like a wipe.</p>

<p>I declared a PQ to store some nodes and i want to store the nodes in non-decreasing order according to the f value.function f(Node node) is to calculate the f value for the node. so i override the comparator but right now i found that some nodes with larger f value are placed before the ones with smaller f value in the queue, i checked all over but still cannot find what goes wrong, i assume maybe it is the PQ declaration's problem. Anyone can help me? Thanks in advance!</p>

4,736,142 | 4,736,143 | How can I bind events to HTML generated after the page loads? | <p>I'm using jquery <code>.clone()</code> to add HTML to my page according to user clicks.</p>
<p>I'd like to add onclick handlers to the newly created HTML. I know <a href="http://api.jquery.com/on/" rel="nofollow"><code>.on()</code></a> can be used to trigger events on future-created HTML, but I believe that must be written (and executed) <em>before</em> the HTML is created.</p>
<p>In this <a href="http://jsfiddle.net/thunderrabbit/Zxq2E/" rel="nofollow">example code</a>, if the user selects "related_id" from the select list, jquery creates a field where the user can enter ids. I'd like to add an ajaxy thing here so the user can type the name of the related item instead of its id. The ajax request will depend on which field the user selected.</p>
<p>Generally speaking, I know how to make ajax requests with jquery, but how do I add the field-specific ajax code to my freshly created HTML?</p>
