Q:

Static Variable interference ASP.net?

I am quite new to Web Development and ASP.net
but i was wondering the following question:
If I declare a static variable on a web page and several
users access the same page simultaneously. Is this static
variable unique to each user or will it interfere with 
different users?
Thanks

A:

Yes, it will interfere between users, and between concurrent requests by a single user. Avoid static fields in ASP.NET (and most other development) unless you are very sure about what you are doing.
Consider using session-state for what you are doing here, or something as part of the request itself (form data, cookie, etc).
