Chapter 1. Version 1.2.1

1.1. Introduction

The DX Object Storage SCSP Proxy is a reverse proxy that provides an interface to the storage

cluster. The proxy accepts HTTP requests from the host network, forwards them to the internal

storage cluster, handles redirects transparently, and then supplies the response back to the

requestor.

Thank you for using the DX Storage SCSP Proxy 1.2.1 release!

1.2. Changes in Release 1.2.1

The SCSP Proxy now better handles a DX Storage cluster being restarted while the Proxy is

running. In previous releases, the Proxy sometimes logged multiple unhandled exceptions when

attempting to contact a cluster that had been restarted, generating an excessive number of log

messages.

Release 1.2 Beta 1 includes the following changes:

• The SCSP Proxy intercepts GET / and HEAD / requests and responds with information it stores

internally about itself and about the cluster for which it serves as a forward proxy. Only GET / and

HEAD / requests result in this type of special handling by the Proxy.

• The Proxy now supports the use of named objects in DX Storage version 5.0 and later.

• The AggregateInfo method can be used as follows with named objects:

{uuid [mutable|immutable] | url-encoded-name}

Release 1.1 had the following changes:

• The SCSP Proxy installer and uninstaller now properly updates the hosts.cfg file after an

upgrade.

• A proxy memory issue that could consume increasing amounts of RAM has been resolved.

1.4.1. Limitations of this Release

These are the known issues and operational limitations that exist in this 1.2 release of the DX

Storage SCSP Proxy.

• Proxy connection timeout. If no DX Storage nodes are online at the time the Proxy is started, an

HTTP client cannot connect to Proxy. The Proxy returns either a 504 (Gateway Timeout) error or

a connection timeout.

To troubleshoot connectivity issues, do the following in the order shown:

Verify whether or not the Proxy is running.
