Re: remoting object access information from local xml file frequen

Thanks Beth.. It was very useful.. it is efficient in using memory ..


One more approach i am thinking.. since all the calls in IIS (remoting
object hosted )
why dont we use the "HttpContext.Current.Application["Schema Owner"]" (sample)
to fetch the data..

will it hold data in IIS memory automatically after retreiving from the
web.config...?
may be after first call... for accesing this value

what do you all think about this?
