Recommended improvements

The proxy might be improved in the following ways:

• Some security measures could be added, giving restrictions to what user may use the proxy. This would be similar to the MIT proxy, which can be configured to only serve users coming from the MIT domain.
• Add encryption to the cache, giving clients increased privacy.
• Use a more elaborate expire scheme, instead of just a constant timeperiod. This could be implemented as an incremental increase in expire time for each cache hit.
