[Mod_gzip] SEND_AS_IS:RESPONSE_CONTENT_TYPE_EXCLUDED

[Markus Heinisch]

Hi,

I have installed mod_gzip-1.3.26.1a in Apache 1.3.27 on Windows 2000. mod_gzip compresses fine (static html,...) except responses from the web-to-go handler, which is a module from Oracle to generate dynamic output (incl. JSP applications).  The mod_gzip.log file lists a lot of 'errors' like:

GET /webtogo/tutorial/ToDoList.jsp HTTP/1.1" 200 - mod_gzip: SEND_AS_IS:RESPONSE_CONTENT_TYPE_EXCLUDED In:0 -< Out:0 = 0%

or

GET /webtogo/WLTop/server HTTP/1.1" 200 - mod_gzip: SEND_AS_IS:NO_CONTENT_TYPE_IN_RESPONSE_HEADER In:0 -< Out:0 = 0%

or

GET /webtogo/dummy.html HTTP/1.1" 200 - mod_gzip: SEND_AS_IS:NO_200 In:0 -< Out:0 = 0

What goes wrong??

Can't mod_gzip compress output from the web-to-go handler?

Can anybody help me, please?

Sorry, the http://www.schroepl.net/projekte/mod_gzip/status.htm gives me a hint to solve the problem.

I have added the interesting lines of my HTTPD.CONF file:
