ProxyReverse Issue on - httpd-2.2.29

[Otis Dewitt - NOAA Affiliate <otis.dewitt@xxxxxxxx>]

Can someone please tell what I am doing wrong here, I am using Apache reverse proxy. I have been having this issue for sometime.

#WORKS

1. If I use the Internal url directly to the server.

  a. https://example.com:20201/class/page/createpdf.jsp?requestId=7

  b. I get a pdf to download. 

# FAILS

2. If I use the External url I get "might be temporarily down or it may have moved permanently to a new web address."

  a. https://www.docuzzzz.com/class/page/createpdf.jsp?requestId=7

  b. "Web Page Not Available" - "The webpage at https://www.docuzzzz.com/class/page/createpdf.jsp?requestId=7 might be temporarily down or it may have moved permanently to a new web address.

Error code: ERR_INVALID_RESPONSE"

# Class Directive (443) #EXAMPLE

RewriteRule ^/class$(.*) https://www.docuzzzz.com/class$1 [L,NC]

<Location /class/>

        SetOutputFilter   proxy-html

        ProxyPassReverse  https://example.com:20201/class

        ProxyHTMLEnable   On

        ProxyHTMLExtended On

        ProxyHTMLURLMap   http://example.com:20201/class  /class

        RequestHeader     unset  Accept-Encoding

Thanks,
