ASP Classic 3.0 Support
Support for ASP Classic 3.0 is provided by an ISAPI extension
(Internet Server Application Programming Interface), named
asisapi.dll. The script execution is
handled by Microsoft Windows Script technology. This technology has
some limitations, resulting in some limitations for ASP Classic
3.0. DWebPro provides also some additional features to ASP Classic
3.0 that extend the original Microsoft ASP support. You can read
more details about these limitations and improvements below.
Due to the technical limitations of the Microsoft Windows Script technology script execution for support of ASP Classic 3.0, the following limitations are in place:
-
The execution of scripts with different languages cannot occur at the same time (for example, in the same ASP page). A beta version of ASP Classic 3.0 support with multilanguage support is available in the
aspisapi\betafolder. To try it, copy theaspisapi\beta\aspisapifile into thedeploy\engine\aspisapifolder. -
Only the VBScript and JScript scripting languages are supported.
-
The
Session.LCIDproperty has no effect when using JScript. -
Some properties of the
ASPErrorobject do not have correct values. For example:-
ASPError.FileandASPError.Lineare not precise -
ASPError.Number,ASPError.Description, andASPError.ASPDescriptionare based on Microsoft Windows Script errors -
ASPError.ASPCodeandASPError.Categoryare empty
-
- In the
GLOBAL.ASAfile, theServer.MapPathmethod must be used with virtual paths (paths relative to the document root). Note that theGLOBAL.ASAfile must be placed in document root (deploy/www) folder.
