gzip encoding on back end web server using SSL with NAM

When trying to access back end Liferay web server, accelerated by the Access Gateway over SSL, users complain about not being able to view the contents of the pages.

After enabling the proxy in debug mode, the following errors are seen in the /var/log/novell-apache2/error_log file:

Jan 30 10:25:30 namtestgw1 httpd[6643]: [error] AMEVENTID#199: Insufficient data for inflate
Jan 30 10:25:30 namtestgw1 httpd[6643]: [error] AMEVENTID#199: Zlib: Validation bytes not present

Running the MAG apache process in debug mode shows the following additional info:

The Access Gateway should not be compressing when Enable 'Force HTTP 1.0 to Origin Server' is enabled, but users still getting the same errors when this parameter was set.

Setting:
In Admin Console under Access Gateways | Edit | Reverse Proxy | Proxy Service | Web Servers Tab |  Enable Force HTTP 1.0 to Origin

On the back end Liferay server, multiple compression options exist:

java.util.zip.Deflater - gzip.compression.level=-1 (can be set from -1, to 0-9)  Tried setting it to -1, 1 and 2 but the results were all the same with error - "Zlib: Validation bytes not present"

com.liferay.portal.servlet.filters.gzip.GZipFilter - Set this parameter to false in order to completely disable gzip encoding on the Liferay web server.

The AG Appliance is no longer throwing the Zlib error.
Able to remove the HTTP 1.0 option to the web server as well.
