Introduction – IP Ranges
The IP Addresses page allows administrators to assign default
profiles to unsigned users that access the MetaLib User Interface (/V).
For example, users that access the UI from within the campus network
receive a default profile of <Portal>-<LNG>-IN, while others receive
the profile <Portal>-<LNG>-GUEST.

This page contains the following sections:
•Create a New IP Range — allows you to add a new IP range for
the specified institution
•List of Defined IPs — displays the list of IP ranges that are
defined for the specified institution
In addition, you can perform the following actions on each IP

Proxy
This field defines the start and end IP address of the IP range. The
following rules apply to IP ranges.

Each IP address must be of the following format, where
<nnn> is 0 to 255:
<nnn>-<nnn>-<nnn>-<nnn>

An IP range cannot overlap an address of another IP range.
This field assigns the default profile to the IP range.
This field indicates whether a proxy server is used for the range of
IP addresses. Select one of the following options:

No Need for Proxy

Use Proxy Server

Introduction – Proxy Servers
Institutions with proxy servers can configure their proxy servers to
work with MetaLib via the Management Interface. Proxy servers are
used in the following ways:
•To link to the native interface of resources using HTTP access
•For MetaLib searches in remote resources
From the Proxy Management screen , you can perform the
following actions:
•Add a new proxy by clicking the ADD PROXY button, which displays
the Proxy Details page
•Edit an existing proxy by clicking the E button next to the proxy that
you want to modify
•Delete a proxy by clicking the D button next to the proxy that you
want to delete

Configuring Proxy Servers
MetaLib supports the use of proxy servers for the following purposes:
•To allow users to link from MetaLib to the native interface of resources via the
institutional proxy server. This means that MetaLib forwards URLs to the siteʹs proxy
server so the proxy server can redirect them to the target resource
•For performing MetaLib searches via a local proxy server. This is especially
important in a consortia environment, where the MetaLib server is located in one of
the institutions of the consortia. In such cases, searches can be channeled via the
relevant local institutional proxy server, enabling vendors to identify the institution
from which searches are performed. Use of a proxy server for the link‐to‐native
interface purpose can be controlled at the resource level by setting the proxy server
flag in the IRD record and also by IP ranges. The use of a proxy server for search
purposes can be controlled only at the resource level.
NOTE: The use of the search proxy server in MetaLib is supported for the
HTTP based resources only.

Configuring Proxy Servers - Filters
IRD_SELECTIVE: The proxy server should be used selectively. In this case,
the system checks the flag in each IRD record to determine if the proxy should
be used. The proxy server is used only if the Proxy Server Flag is set to Y in
the resourceʹs IRD record for link to native interface using the proxy server, or
if the Search Proxy Server Flag is set to Y in the resourceʹs IRD record for
search using the proxy server.
IP_SELECTIVE (used only for Link to Native proxies) This indicates that the
proxy server is used selectively. The system checks the IP of the user. The
proxy server is used only if the user is outside the IP ranges defined in the
./vir00/tab/ proxy_<institution>.config table.
LOCK (used only for Link to Native proxies) This indicates that the users
should be directed to the proxy server for the resources they are authorized to
use.
