Hello Guys

I am using virtual Directories in my websites.
and using asp/sql based application with IIS-5 on windows 2000 server, server has 2GB of RAM with Intel pentuim-IV processor,

some common asp files are placed in a folder available through virtual directories to multiple sites hosted on the same server, these common files are used all over the site pages. Load on each site is increasing day by day and I am facing some performance issues, with increase in traffic on the sites.

Many of the site visitors are complaining that they are facing bad request errors (http 400), sometimes its DNS err and sometimes its something else. (I guess its not internet connection problem, because Error vanishes as soon as I refresh the page or submit the form again by using browser back button).


I have checked the programming and nothing seems to be wrong but the behaviour is uncertain


Now, what I want is to know if there is any DRAWBACK of using Virtual directories?
Could this be the problem just because of virtual directories?


Please help me guys!
