Creating browser sniffer with ASP.Net

[David Baker]

Hi all

I am very new to ASP.Net. I am trying to create a sniffer for our program. We want our users to click our sniffer and hopefully the sniffer will check their computer against our requirements. I would like to ask experts like you to see which items are actually doable with ASP.Net. Below I listed all of the items we are looking for but I can understand if some of the items are impossible to check/sniff. We would like to create a sniffer that returns the results for the below items

Broswer (minimum requirement is I.E. 6 for PC and Safari for Mac OS X
Browser type (This area will tell them what they have -AOL, MSN, IE...etc and in the list returns a red gif image if they don't have IE 6 or Safari
Browser version (This area will tell them what version they have and again returns a red gif image if they have an earlier version
Cookies (In this area we are basically trying to find out in the browser window - just for IE - if their privacy setting is set to the following: The window name is: Advanced Privacy Settings. We want "Override automatic cookie handling" to be checked; first-party-cookies and third-party-cookies radio buttons are checked and "Always allow session cookies" are checked. We also want if our website is listed in the "Per Site Privacy Actions" window (you can get to window by clicking in IE Tools-Internet Options-Privacy-Websites-Edit)
Cache (In this area we are trying to find out if their "Temporary Internet Files" settings is set to "Every visit to the page"
OS Version (This area will tell them what version they have and returns a red gif image if they don't have Windows XP or Mac OS X
Connection speed (This area will tell them what their connection speed is and returns a red gif image if they have dial-up connection
Display settings (This area will tell them what their screen resolution is
Service Pack ( This area will tell them if they have Service Pack 1 for Windows XP
Flash (This area will tell them if they have Flash plug-ins
Java (This area will tell them if they have Java Virtual Machine
Java Applets (This area will tell them if they have some of our applets installed in this directory: C:\WINNT\Downlo aded Program Files
Java Script (This area will tell them if some of the items in browsers "Security Setting" window (IE-Tools-Options-Security-Custom Level
Adobe Acrobat Reader (This area will tell them if they have Acrobat Reader 6.0
Do you have a media player? (This area will tell them if they have any media player (Windows Media, Real player, Winamp...etc
What program will open TIFs (This area will tell them what program is associated to open with the files with the extension .tiff
Firewall check (This area will tell them if they are behind a firewall
Pop-up window check (This area will tell them if there is any program that is blocking pop-up windows such as search toolbars
Parasites (This are will tell them if they are infected with parasites

Thank you in advance. Any ideas would help

Hi David,

This article will show you pretty well all of the info you can get using the
Request object in ASP.NET:

That's a heck of a lot more information than their browser is going to send
with a Request. You will need to write an ActiveX Control or Java Applet to
run on the client and perform this type of testing.

Thank you both for replying. From what I understand from your replies, I have two options: either use ASP.Net and create a server-side scripting (which Kevin says it is difficult to accomplish) or create a client-side scripting (using Active X or Jscript). Is that correct? If so, which path do you recommend me to go

Thanks a bunch, this information is very useful to get started

Hi Dave,

I think you're going to need an ActiveX control or a rich .NET client to get
what you need. You've got to search for stuff on the drive and in the
registry.

The control would be along the lines of what they use at Windows Update. The
user is going to have to accept the security warning in the browser before
the control can start scanning.
