## Why does proxying maven.oracle.com require a special configuration?

Oracle requires a complicated interaction that involves authentication, large numbers of HTTP redirects, and session cookies for a single content download. These requirements are not typical of other remote URLs you might usually proxy.

More information about Oracle's Maven repository is at [http://www.oracle.com/webfolder/application/maven/doc.html](http://www.oracle.com/webfolder/application/maven/doc.html)

## Nexus Repository 3.2.1 and greater

Nexus Repository 3.2.1 and greater can [proxy](https://help.sonatype.com/display/NXRM3/Repository+Management#RepositoryManagement-ProxyRepository) maven.oracle.com

Proxying `https://maven.oracle.com` requires [special HTTP options](https://help.sonatype.com/display/NXRM3/Repository+Management):

- _Enable circular redirects_ must be checked
- _Enable cookies_ must be checked.
- Valid Oracle authentication credentials must be entered for the proxy repository

By enabling these options, you allow the repository manager to maintain the authentication state in a cookie that would be sent with each request, limiting the need for authentication-related redirects and avoiding timeouts.

## Nexus Repository 3.0 to 3.2

Nexus Repository 3.0 to 3.2 versions do not have support for proxying maven.oracle.com.

## Nexus Repository 2.11.2 and greater

Nexus Repository 2.11.2 and greater can be configured to use a Maven 2 proxy repository to `https://maven.oracle.com`:

1. Edit `${NEXUS_INSTALL_DIR}/conf/nexus.properties`, by adding these lines:

```
   # Comma separated list of hostnames that needs to accept circular redirections
   nexus.remoteStorage.enableCircularRedirectsForHosts=maven.oracle.com
   # Comma separated list of hostnames that benefit from using cookies
   nexus.remoteStorage.useCookiesForHosts=maven.oracle.com
   ```

2. Start or restart Nexus Repository to pick up the changes
3. Create an Oracle Maven 2 proxy repository using `https://maven.oracle.com` as the remote URL. Enter your Oracle credentials into the _Authentication_ section of the repository configuration.

The Nexus Repository 2 Browse Remote feature does not work with the Oracle repository. Oracle does not support browsing the directory listing of their repository.
