Problems with Google Search Appliance and Domino’s compressed HTTP output

If you use Domino’s HTTP GZIP compression, you may have issues with your Google Search Appliance reporting:

Malformed HTTP header: empty content

It appears that the Google box will tell Domino that it accepts compressed content in the HTTP headers even though it is unable to process the content. Luckily I found an easy solution on the Google Search Appliance support forum.

The solution is to add headers to the Google Box’s http requests.

  1. Open the GSA admin interface.
  2. Select ‘Crawl and Index‘ -> ‘HTTP Headers
  3. In the ‘Additional HTTP Headers for Crawler’ enter:

Accept-Encoding: *;q=0
