Hi Greg,

They are generally HTTP status codes but in a few cases we have added
some TDS specific codes. Here are the only three TDS specific codes:

    * "1000 (Client Abort)" - the connection to the client was broken;
    * "1001 (Forwarded)" - the request was forwarded to another TDS
internal service; or
    * "1002 (Forward Failed)" - an attempt to forward the request to
another TDS internal service was made but failed.

These codes only show up in the TDS debug logs. They don't ever show up
in the access logs.

New addition to the TDS reference docs that cover these codes:

TDS Logging -

Hope that helps,

Ethan
