IIS

Main components for SVCHost.exe are WWW Publishing Service (W3SVC) and Windows Activation Porcess (WAP) .

W3SVC is the mediator of HTTP.SYS and Windows Activation Process. Windows Activation Process maintain the worker processes.

We can easily debug any web application that are hosted on IIS by using Attaching of Worker Process.

From Visual Studio IDE > Tools > Attach To Process

Select the particular Process, then start debugging.

ecycling Application pool means recycle the Worker process (w3wp.exe ) and the memory used for the web application.

There are two types of recycling related with Application pool

1. Recycling Worker Process - Predefined Settings

2. Recycling Worker Process - Based on Memory

Open IIS and right click on Computer in IIS.

Select Internet Information Services. Now goto All Tasks Backup/Restore Configuration.

Click on create backup and give the backup name.

1. Read

2. Write

3. Execute

4. Browse

5. Run Scripts

Two types of layers in IIS:

Kernal Mode

User Mode

Under Main Layers sub contents are:

1.Kernel Mode

HTTP.SYS

2.User Mode

Web Admin Service

Virtual Directory

Application Pool

1. DefaultAppPool (Integrated)

2. ClassicAppPool

Hosting webapplication in multiple webservers using load balancer is called as Web Farm.To avoid the high load in single server this load balancer method will use to distribute the traffic to different server on same web application.

1. Recycling Process

2. Performance

3. Health

4. Process Identity

From Run -> inetmgr

Start -> Programs -> Administrative tools

Before answering this question you need to know what are the different IIS version is available in different OS. Below is the list of IIS version with different Operating system.

Windows Server 2008 - Windows Vista - Home Premium/ Ultimate - IIS 7.0

Windows Server 2003 - IIS 6.0

Windows XP Professional - IIS 5.1

Now based on your working experience you can say that you have worked on IIS 5.1 and 6.0 or only IIS 7. Etc.

Now, the next question that can asked after answering this question is “what is the difference between them ? ” – Well I will come with this later.

Below are the commonly used IIS Security settings

1 Anonymous

2 Integrated Windows Authentication

3. Basic Authentication

4. Digest Authentication

5. Passport Authentication

For Set security permission you need to go to Virtul Directory > Right Click > Properties > Directory Security

Click on Edit Button .

We can set the default page for a web site from the Virtual Directory Setting.

How To :

IIS Manager > Virtual Directory > Right Click > Properties > GoTo Document Tab.

We can hosted site on IIS either creating Virtual Directory through IIS manager or Using Folder Web Sharing .

Apart from that Visual studio provide some inbuilt features to host the site on IIS like using Publishing the web site , Using Copy web Tool or Creating Virtual directory during the creating the project by choosing Location as HTTP

HTTP – 80

SSL – 443

FTP – 21

SMTP – 25

POP3 – 110

IMAP – 143

NNTP – 119

LDAP – 89

Other Port Number:

DNS – 53

DHCP : 67

We can set the Idle time out for an worker process from Application Pool Properties.

In Performance Tab of Application pool, we can set the Idle Time out of the worker process. This means worker process will shut down after that given time period if it stay idle. And will again wake up again if a new request comes.

Default Identity of IIS 6.0 is NetworkServices .

Which is having very minimum rights on your system. The user can only have the read access of the site.

First identify the Application pool name and process ID using cscript iisapi.vbs script.Later attach process from Visual Studio IDE.

For IIS 6.0 > w3wp.exe

For IIS 7.0 > w3wp.exe

in IIS 5.1 worker process is aspnet_wp.exe.
