HOWTO: Changing the URL and reloading the dataset

Question

Sometimes, you will need to change the url of your dataset
and reload the dataset. This is quite easy to do with changing a
variable and calling a method. Below is the code you would use. I
use it to page through a set of data which only comes back in 10
row increments and we do not know the recordcount of. (Yippee,
Oracle E1). Anyway, here's the code....
<script type="text/javascript" language="javascript">
rowCount = 0;
dsPeople = new
Spry.Data.XMLDataSet("/spry/?event=peopleSearch&srchRowStart="
+ rowCount,"/orders/row", { useCache: false });
function changeRowCount()
rowCount = rowCount+10;
var spryURL = "/spry/?event=peopleSearch&srchRowStart="
+ rowCount;
dsPeople.url = spryURL;
dsPeople.loadData();
</script>
<div spry:region="dsPeople">
<div spry:state="loading"><img
src="/assets/images/ajax-loader.gif"/></div>
<div spry:state="error">Error Loading
Data...</div>
<div spry:state="ready">
<div spry:repeat="dsPeople">
<span spry:content="{dsPeople::NAME}"></span>
</div>
<a href="javascript:changeRowCount()"><span
spry:content="Next 10 Records"></span></b>
</div>
</div>

Answer 1

Enabling SSL for Central Administration is a good idea. Making it so it is only accessible using an IP address doesn't make it any more secure. This is security through obscurity and anyone dedicated enough to attacking Central Administration will find the
site whether it's an IP address or named.
For what it's worth an attacker is going to try scanning IP ranges long before they try looking at DNS. And, because of the way SharePoint works if the site is accessible by its IP address and not a specific hostname, anyone who knows the IP address and
the SSL port (443) can connect. If you have a hostname it won't be immediately accessible.
Some other thoughts: When you rely just on the IP address, what happens if you want to move Central Administration to another server in the farm, or you want to provide load balancing and have multiple servers hosting Central Administration? What happens
when the server running Central Administration dies so you create a new Central Administration site on a server with a different IP address? How will you communicate this URL change to all of your administrators?

Sorry,
I wasn't clear in my OP.  The IP would be tied to a DN.  So you would go https://abc123.com and it would ask for authentication.  That URL would be tied to a separate IP on the network card of that server.  The IP address association
is done through IIS.
