Hidding IIS web server header

By on July 9, 2010


Google for long time regarding how to hide the HTTP header for IIS in order to mask the server identity and finally found out this tools call URLScan.
Basically URLScan is an ISAPI filter that allows Web site administrators to restrict the kind of HTTP requests that the server will process. By blocking specific HTTP requests, the URLScan filter prevents potentially harmful requests from reaching the server and causing damage.
Actually most of the features that provided by URLScan are included in IIS but not the Remove Server Header features as microsfot find out that this is not an important issue that that’s no real security benefit of include in IIS. But that’s some marketing purposes why microsoft not encourage web master to hide the identity.

How to hide the IIS identity:

  1. download the URL scan
  2. Install the URL scan in your server.
  3. go to the URLScan config file at C:\WINDOWS\system32\inetsrv\urlscan\UrlScan.ini
  4. Change RemoveServerHeader=1 (by default is 0)
  5. Save the file
  6. Restart your IIS
  7. Check on your header (http://www.rexswain.com/httpview.html)
For more detail on the URLScan and the features, you may easily get a lot of information by Google on URLScan

Get the array lenght in Coldfusion

By on September 4, 2009

When dealing with array, we cannot run away for looping. Because only with looping, you can cut short your hard coded script to read the value from array. And also you no need to worry about the dynamic of array.


Arraylen is the function that determines the number of elements in an array.


The syntax is ArrayLen(array)


Code

<!— Assigning value into 3D array —>

<cfset ResultsArray[1][1][1] = ‘a’>
<cfset ResultsArray[1][1][2] = ‘b’>

<cfset ResultsArray[1][2][1] = ’3′>
<cfset ResultsArray[1][2][2] = ’4′>

<cfset ResultsArray[2][1][1] = ‘z’>
<cfset ResultsArray[2][1][2] = ‘x’>

<cfset ResultsArray[2][2][1] = ‘m’>
<cfset ResultsArray[2][2][2] = ‘p’>

<cfset ResultsArray[3][1][1] = ‘ww’>
<cfset ResultsArray[3][1][2] = ‘xx’>

<cfset ResultsArray[3][2][1] = ’22′>
<cfset ResultsArray[3][2][2] = ‘cc’>


<!— Read the array lenght for 1st D, 2nd D, and 3th D —>
<cfoutput>
#ArrayLen(ResultsArray)#<br> <!— Get the lehgth of 1st D —>
#ArrayLen(ResultsArray[1])#<br><!— Get the lehgth of 2nd D —>
#ArrayLen(ResultsArray[1][1])#<br><!— Get the lehgth of 3th D —>
</cfoutput>
