Goodies Thoughts - Easy Server Administration
Back in October of last year, I wrote about an alternative
hosting solution for smaller websites. The solution involved the use of a
virtual server -- a setup within the hosting company's server that looks and
behaves to the user as if it was a complete system itself. The piece can be
The solution provided an example hosting company called Aplus.net (for more info contact Liz Zacharieva, firstname.lastname@example.org or visit http://www.aplus.net)
Following that piece, I have received questions from some readers concerning the amount of knowledge of Unix (and Unix-like systems) they would need in order to run their own virtual server.
While it's true that most of the lower cost servers are running one or another flavor of Unix, they mostly also have a very powerful web based administration tool installed on them. This tool is called Webmin (http://www.webmin.com), and is a product mostly developed by Jamie Cameron (email@example.com) and offered under a license for free commercial and non-commercial use. Even if the server you get doesn't have Webmin installed, the instructions provided on their site make downloading and installing a breeze.
With Webmin installed on the system, almost all administrative functions are performed through the web interface. No Unix knowledge required! The most Unix you'll need is for downloading and installation and those instructions are pretty much step by step.
Aplus.net is not currently offering any more virtual server solutions, but I notice that they do have a "Value Server" offering. These are systems that were in use by other customers, but are no longer, and are not "state-of-the-art". They are, however, a great value and would provide plenty of power for hosting some smaller sites (i.e. less than million-a-day e-commerce sites!) When I checked just now, they had 29 of these left at $49/mo each. In a short while there will be 28! (I like to keep a few things spread around the world!)
Thanks for Reading!

Questions are taken from submissions to our Community Mentors. You can ask a Mentor a question by going to http://www.htmlgoodies.com/mentors.
Q. I have a domain name that I keep my website posted at. But I also use folders on my site that I do not link to from anywhere in my site. These are just folders for me that I can create pages of reference material that I can look up on the go. I would like to be able to give the address for these pages to certain people but for the most part want to keep them private. Is there any way that I can keep them from showing up in search engines, or some code that would render them invisible to search bots. I don't want to password protect the pages I just want to make it harder for people to stumble onto them without knowing the link.
A. You can tell the search engine robots which folders should and should not be indexed by them. It is called The Robots Exclusion Protocol. When a robot visits a web page it first looks for a file named ROBOTS.TXT. This file contain the information about which parts of the site should nojt be visited by the robot.
The Robots META tag lets you tell the robots if a document should be indexed or not:
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
Only a few robots support this way.

The Web Robots Pages:
Q. I am trying to find a way to post my students' grades to my webpage, while insuring individual privacy. I have learned from the tutorials how to include a password to keep the grades private. As far as I can tell, I should be able to make an individual web page for each student and have the password link to that page, showing them their grades. I have 70 students and do not look forward to editing 70 pages each time I have to update grades. Is it possible to store the grade information in one place and have each individual page find and display the info for the appropriate student?
Q. Used this bit of code:
img1 = new Image ()
img2 = new Image ()
img2.src = "images/noahnick.jpg"
img3 = new Image ()
img3.src = "images/kevinnick.jpg"
img4 = new Image ()
img4.src = "images/mikekevin.jpg"
img5 = new Image ()
img5.src = "images/noahkevin2.jpg"
slide show opens - goes thru each image, after the last slide it looks
for an image that isn't there instead of looping to image #1. Same
problem in reverse Any suggestions?
A. Try setting the initial value of the variable num to zero instead of 1. In your function you add 1 to it as the first step. Also in your function slideshowUp when num has a value of 6 set it to zero instead of 1. In your function slideshowBack try setting num to a value of
6 when it reaches 0 so that when you subtract 1 again it will be set to 5.
Q. I have a song loading on the first page of the website. I would like that song to continue playing throughout the website with the ability to be turned off at any time. Could you please tell me how to load it so it doesn't start over with the selection of any page link?
A. The way the site is set up now you cannot have the music playing without re-starting on each page. If the entire site was done in Flash it could be done if the information being sent to the browser was only sent once. Because each page loads separately the song is going to keep re-starting.

ASP.NET Mixed Mode Authentication
In many web applications it is desirable for both intranet users and external parties to be able to seamlessly log onto the system. The problem this raises is that it is not easy to allow intranet users to log in via Windows integrated authentication while also allowing external parties to log in to the same application using standard forms authentication. This article will show you one way to achieve the best of both worlds when it comes to authentication.

XML to HTML (via XSL) Using the XML Server Control ASP.NET Sample Code
A while back I wrote a sample that takes an XML file and an XSL file and combines them to produce appropriately formatted output. It's quite a handy little script and I've been using here and there for things like menus and navigation bars. While the original sample was only a dozen lines or so, it has recently come to my attention that there's an even easier way to accomplish the task in just one line of code.

Passing Parameters from One Page to Another
