ASP.NET - IIS isolation levels - Dec 25, 2009

Explain different IIS
isolation levels in ASP.NET- Low (IIS process A), Medium (Pooled), High
(Isolated)
Low (IIS Process):
This
is the fastest and the default IIS4 setting. ASP pages run in INetInfo.exe and
so they are executed in-process. If ASP crashes, IIS too does and must be
restarted.
Medium (Pooled):
This IIS setting is more reliable. In this if ASP crashes, IIS does
not. In this, the ASP applications share the same process, so a web site can
run with just IIS and ASP process. IIS5 supports this setting and is the
default setting.
High (Isolated):
This setting runs in MTS.EXE in IIS4 and in DLLHOST.EXE in IIS5. If
one ASP application crashes, IIS or other ASP applications don’t crash. Each
ASP application runs out-process in its own space.
Authentication is the process of verifying user’s details and
find if the user is a valid user to the system or not. This process of
authentication is needed to provide authority to the user........
WCF can create services similar in concept to ASMX, but has
much more capabilities. WCF is much more efficient than ASP.Net coz it is
implemented on pipeline............
Users of different countries, use different languages and
others settings like currency, and dates. Therefore, applications are needed to
be configurable as per the required settings based on cultures, regions,
countries.........
