IIS 7.0’s Componentized Strategy
Metabase
WMICompatibility
LegacyScripts
LegacySnap-in
IIS 7.0 Componentization
Slim & Efficient
Install only the components you need
Reduce attack surface to minimum
Five times more granular than existing
IIS versions
Servicing and patching on a per
component basis
If you don’t install it, you won’t need to
patch it
Customizing the Web
Server Core

IIS 7.0 Extensibility
Today’s “Request Pipeline”
w3wp.exe
aspnet_isapi.dll
handlers
cgi
static
file
Isapi
exts
url map
determine handler
begin req
logging
auth’c req
custom errors
auth’z req
compression
resolve cache
end req
authentication
handler map
update req cache
handler exec
rel req state
ISAPI Filter Notifications
w3svc
IHttpModule Events
url map

IHttpHandlers
Pre-proc headers End net session

IIS 7.0 Extensibility
Modular server for customizable footprint
All modules built on public APIs - add,
remove, or replace
Native (C/C++) and Managed (C#,
VB.NET) extensibility
Deep Integration across IIS & ASP.NET
Configuration
& Delegation
Configuration Today in IIS 6
Metabase
Single, centralized configuration store
Accessed at runtime via IISAdmin service
Delegation not well supported
Not strongly schematized
Difficult to extend
IIS 6 Configuration Sample

<IIsWebService Location ="/LM/W3SVC"
ScriptMaps=".asp,D:\WINDOWS\system32\inetsrv\asp.dll,5,GET,HEAD,POST,TRACE
.idc,D:\WINDOWS\system32\inetsrv\httpodbc.dll,5,GET,POST
.shtml,D:\WINDOWS\system32\inetsrv\ssinc.dll,5,GET,POST”
… (other properties here)
>
</IIsWebService>
<IIsWebVirtualDir Location ="/LM/W3SVC/1/ROOT“
ScriptMaps=".asp,D:\WINDOWS\system32\inetsrv\asp.dll,5,GET,HEAD,POST,TRACE
.idc,D:\WINDOWS\system32\inetsrv\httpodbc.dll,5,GET,POST
.shtml,D:\WINDOWS\system32\inetsrv\ssinc.dll,5,GET,POST
.aspx,D:\WINDOWS\Microsoft.NET\Framework\v2.0.x86chk\aspnet_isapi
.dll,1,GET,HEAD,POST,DEBUG”
… (other properties here)
>
</IIsWebVirtualDir>
IIS7 Configuration
No more metabase
Distributed configuration files
Decentralized – worker processes read
config files directly
Supports delegation
Clean, well schematized configuration files
Rich extensibility
IIS7 Configuration Sample
<!– ApplicationHost.config -->
<handlers>
<add path=“*.asp" modules=“Asp“ checkPathInfo=“true“
verb="GET,HEAD,POST" />
<add path=“*.stm" modules=“ServerSideIncludeModule”
checkPathInfo=“true" verb="GET,POST" />
<add path=“*.exe" modules=“CGIModule“ checkPathInfo=“true"
verb="GET,POST" />
</handlers>

<handlers>
<add path=“*.aspx“ modules=“aspnet” checkPathInfo="false” verb="GET,POST" />
<handlers>
Configuration Delegation
