Set header based on %{REQUEST_URI}

Question

I am trying to set a header based on the URI of a particular page.

I access a page using chrome. Inspect element and see that my URI header is giving the value /bst/index.html Now in my Apache config , I want to set a Header to Yes if my %{REQUEST_URI} is equal to /bst/index.html This is what I am doing :

RewriteCond %{REQUEST_URI} ^\/bst\/index\.html [NC]
Header set X-Akamai Yes

The above config is not working and is setting X-Akami for all the pages I am visiting on the web page.

Any idea why ?

<If "%{REQUEST_URI} =~ m#^/bst/index\.html#">
Header set X-Akamai Yes
</If>

Thank You Florin. But is "m#^/bst/index\.html#"" this whole a regex ? I mean whats the purpose of m & # in this all ? – Jason Stanley Dec 03 '15 at 03:39
Apologies. I missed out on the fact that there was a second document too. I tried the solution you provided. Gives me the below error when I restart Apache : Syntax error on line 66 of /tools/conf/ssl.regular.conf: Header has too many arguments I will check different solutions. – Jason Stanley Dec 03 '15 at 04:02
Try the first syntax, it definitely works. – Florin Asăvoaie Dec 03 '15 at 04:16

Check the logs. – Florin Asăvoaie Aug 03 '18 at 10:24
Dear thanks for you quick response.error_log is empty ..! – Bhavik Hirani Aug 03 '18 at 10:27
The `` directive was only added in Apache 2.4 . There are some alternatives to it for older versions: https://serverfault.com/a/698192 – Georg Schölly Aug 13 '20 at 13:32

So you downvoted the answer because you are using an unmaintained version of Apache Web Server? Nice! – Florin Asăvoaie Aug 14 '20 at 14:50

For me %{THE_REQUEST} worked better liked this (I changed the regex of "Nestor Urquiza":

<If "%{THE_REQUEST} =~ m# /bst/index\.html#i">
  Header set X-Akamai Yes
</If>

%{REQUEST_URI} will probably just match the last path in the URI (index.html). You probably want to try with %{THE_REQUEST} instead:

<If "%{THE_REQUEST} =~ m#^/bst/index\.html#">
  Header set X-Akamai Yes
</If>

`THE_REQUEST` expands to the full browser request line, including the request method, so this will **never** match. [Check here](https://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritecond) – flaviovs Mar 21 '20 at 00:47
