<OBJECT> Declarations
You can create objects with session or application scope in the Global.asa file by using the extended <OBJECT> tag. This tag is self-contained and is outside of any <SCRIPT> tags.
The objects declared in the Global.asa file are not created until the server processes a script that calls that object. This saves resources by creating only the objects that are needed.
Syntax
<OBJECT RUNAT=Server SCOPE=Scope ID=Identifier {PROGID="progID"|CLASSID="ClassID"}>
. . .
</OBJECT>
Parameters
- Scope
- Specifies the scope of the object. In the Global.asa file, Scope will be set to either Session or Application.
- Identifier
- Specifies a name for the object instance.
- ProgID
- An identifier associated with a class identifier. Either ProgID or ClassID must be specified in the <OBJECT> tag. The format for ProgID is [Vendor.]Component[.Version].
- ClassID
- Specifies a unique identifier for an COM class object. Either ProgID or ClassID must be specified in the <OBJECT> tag.
Examples
The first of the following examples creates an object of session scope named MyConnection by using the ProgID parameter. The second example uses the ClassID parameter.
<OBJECT RUNAT=Server SCOPE=Session ID=MyConnection
PROGID="ADODB.Connection">
REM Object Script
</OBJECT>
<OBJECT RUNAT=Server SCOPE=Session ID=MyConnection
CLASSID="Clsid:8AD3067A-B3FC-11CF-A560-00A0C9081C21">
REM Object Script
</OBJECT>
Remarks
The objects declared in the Global.asa file can be used by any script in the application. For example, if you declared the following object.
---GLOBAL.ASA---
<OBJECT RUNAT=Server SCOPE=Session ID=MyAd PROGID="MSWC.AdRotator">
</OBJECT>
You could reference the object MyAd from any page in the application:
---SOME.ASP---
<%= MyAd.GetAdvertisement("/ads/adrot.txt") %>
