NOSCREENREDIR (JANUS DEFINE parameter)

<section begin="desc" />Don't use REDIRECTs to map Legacy screens.<section end="desc" />

NOSCREENREDIR is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.

Indicates that Janus Web Legacy Support (automatic mapping of 3270 applications to HTML) is not to use the redirect's to map all screens for a legacy session to the same URL. This means that all legacy screens will be maintained as a separate browser cache entry that is a result of a POST to a generated URL. This parameter is only available in Sirius Mods 6.0 and later and its use is discouraged but is provided if for some reason full backward compatibility with earlier versions of Janus Web Legacy Support is desired.

NOSCREENREDIR can be overridden or set on a URL basis with the SCREENREDIR or NOSCREENREDIR parameter in JANUS WEB SCREEN rules.

From Sirius Mods 6.0 to 6.2, NOSCREENREDIR would also cause Janus Web Server to switch to an internally generated URL on the first Janus Web Legacy page. In Sirius Mods 6.3 and later, NOSCREENREDIR prevents a redirect from being used for each page but does not cause an internally generated URL to be used for Janus Web Legacy pages. Use of these internally generated URLs under Sirius Mods 6.3 and later is controlled by the SCREENURL parameter.

This parameter can be overridden on a URL basis by the SCREENREDIR and NOSCREENREDIR parameters on JANUS WEB SCREEN rules.

Valid only for WEBSERV ports.
