Unable to Use Standard Program I/O in PERL Script (156755)
The information in this article applies to:
- Microsoft Internet Information Server 2.0
This article was previously published under Q156755 We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site: SYMPTOMS
You are unable to use standard programming I/O methods to pass arguments
and/or data to and from external command or separate PERL Scripts that are
spawned from a parent script.
CAUSE
When you spawn a script or external command from a CGI application, it is
created in a separate process. By default Microsoft Internet Information
Server (IIS) 2.0 does not create a console and does not support standard
I/O redirection between processes.
RESOLUTION
To resolve the problem, edit the registry as described below.
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
- Start Registry Editor (Regedt32.exe) and locate the following registry
subkey in the HKEY_LOCAL_MACHINE subtree:
\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters
- Click Add Value on the Edit menu.
- Type the following:
Value Name: CreateProcessWithNewConsole
Data Type: REG_DWORD
DateValue = 1
NOTE: Creating a new console for each CGI script has serious performance
implications and should not be done unless slower performance is
acceptable.
MORE INFORMATION
For additional information about supported registry parameters, please see
the Online documentation for IIS 2.0. Go to the product documentation link
and choose Chapter 10 from the contents page then Service Specific Registry
Entries with Common Names. Search on CreateProcessWithNewConsole.
