web application developing & response time

[Shosh]

A:
Web application "response times":
I am looking for ways, standards and/or common guide lines/procedures of defining the requested "response times" of an web application (application items) and testing them?.

B:
"To do and not to do" in developing web application in Dot.Net:
I am looking for any standards or "well known", common knowledge, principles, guide lines and/or any advises in developing web application, especially in regard with:
A) security
B) "transplantation" of cookies, files, etc in the work station memory and/or on the hard-disk?

Thanks in advance

You usng an xml webservice or anything or trying to use soap? By webaplication do you mean using asp.net or an actual internet application that runs peer to peer or through a central server? I do not understand what this responce time you are talking about is, are you talking about the time it take to genorate the code? Basically get a fast data base and keep it organised for the best times if that is the question, like use mssql server instead of access and keep it organised use the identification feilds etc.
