Yes, your mis-configuration is causing your issue.

The extension of a URL has NOTHING to do with whether it is static or not.

Whether the extension of a URL is mapped to some Application Mapping or
not -- that determines whether the resource is dynamic or static.

By definition, static content is just returned as-is. Dynamic implies that
some processing happens on the resource prior to returning a response. In
this case, something has to process the <!--exec cgi=""--> commands... thus,
a .html mapped to ssinc.dll is considered dynamic content.

Hi,
On our server we have mapped .html extension to the ssinc.dll file
since we need to execute .html files as include files (or .shtml).
Does this could be the reason for static compression not happening?
Also as mentioned earlier in almost every .html page that serves from
our page we are including some .asp script files as <!--exec cgi=""-->
files to be executed. Can that also be a cause of this issue?
Please guide..
thanks
Rajiv
