Vary Header

[billo355 Profile]

I am using the most recent version of Helicon Ape.
I have discovered that, when REWRITE is turned on - some responses return a header of:

Vary: Original-URL

This interferes w/ client side caching in IE.

If I turn OFF rewrite - the header no longer appears.

I can't find anything about this in Ape documentation - can you clarify how I can stop the Vary header from being set?

Just to be clear - if .htaccess is:

RewriteEngine on
RewriteRule ^(.*/)*\.private/ http://www.xyz.org/ [NC,R]

I see the VARY header.

If I change it to:

#RewriteEngine on
RewriteRule ^(.*/)*\.private/ http://www.xyz.org/ [NC,R]

There is no header.

The website itself is a .NET 4.0 application.


EDIT: It seems I was mistaken. The RewriteRule above doesn't cause an issue. It functions fine. The following rule (or one like it - w/ a RewriteCond) appears to cause the "Vary" header problem:

RewriteCond %{HTTP:Host} ^proxy\.xyz\.org$
RewriteRule ^([^/]*)/?$ http://www.xyz.org/ [NC,L,NS,R]

It causes the issue even if the condition is not met (and rule not applied.)

Also - I attempted to use Ape to alter the headers - but it doesn't work.
w/ Rewrite on I tried:

Header unset Vary

didn't work (Original-URL) remained. I also tried to "set" or even "append" the header. No luck.

If I turned Rewrite off - I was able to set the Vary header.
