+Interoperability problems have led to the introduction of
mechanisms to modify the way Apache behaves when talking to particular
clients. To make these mechanisms as flexible as possible, they
are invoked by defining environment variables, typically with
<A HREF="mod/mod_browser.html#browsermatch">BrowserMatch</A>, though
<A HREF="mod/mod_env.html#setenv">SetEnv</A> and
<A HREF="mod/mod_env.html#passenv">PassEnv</A> could also be used, for

+<H2>force-no-vary</H2>
+<P>
+This causes any <CODE>Vary</CODE> fields to be removed from the response
+header before it is sent back to the client. Some clients don't
+interpret this field correctly (see the
+<A HREF="misc/known_client_problems.html">known client problems</A>

+this variable also implies <STRONG>force-response-1.0</STRONG>.

<H2>force-response-1.0</H2>
+<P>
This forces an HTTP/1.0 response when set. It was originally implemented as a
result of a problem with AOL's proxies. Some clients may not behave
correctly
when given an HTTP/1.1 response, and this can be used to interoperate with
them.
