Platforms

Non-VM 17.0 and later


Abstract

Numeric value determining at what level LISTSERV indexes lists for the web interface.


Example

z/VM:

<not available>

Unix:

OLD_WEB_INDEXES=0

Windows:

OLD_WEB_INDEXES=0

Note for Unix:  OLD_WEB_INDEXES has been pre-exported in the "go" script which ships with LISTSERV 17.0 and does not need to be exported separately in go.user.

Details

The setting of OLD_WEB_INDEXES determines at what level LISTSERV indexes lists. The options are as listed in the following table (the default value is in bold):

OLD_WEB_INDEXES=0

LISTSERV will create and maintain only new-style single indexes after a list has been indexed from scratch. Old-style indexes are used until the list is re-indexed and are then removed permanently.


This is the "normal" setting for 17.0 and the default.

OLD_WEB_INDEXES=1

Both types of indexes are created when indexing the list from scratch and are maintained in parallel. In other words, re-indexing a list adds a new-style index without losing the old-style index.


This is a hybrid mode for testing only.

OLD_WEB_INDEXES=2

A new-style single index is never created. This setting is supported only with WWW_ALLOW_LEGACY_INTERFACE=2.


This is a compatibility mode only.

OLD_WEB_INDEXES is closely related to the WWW_ALLOW_LEGACY_INTERFACE site configuration variable, and the values of both variables should be considered carefully if there is any reason to change them from the default.  Please see the documentation below for WWW_ALLOW_LEGACY_INTERFACE for more information.
