Subject Re: [users@httpd] Redirect, Rewrite and php.ini
Date Wed, 04 Jul 2007 16:00:29 GMT
I've done some tests adding the header "Control-Cache: no-cache" to the 
requests (using LiveHttpHeaders plugin in Firefox) and (I think) the 
proxy caches can be discarded as the origin of the problem.

With this rewrite rule (jnlp):
--
RewriteBase /herramientas/
RewriteRule ^sincronizar1\.jnlp$ sincronizar.php
--
and this request:
--
GET /herramientas/sincronizar1.jnlp HTTP/1.1
Host: www.electrodh.com
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; es-ES; rv:1.8.1.4) 
Gecko/20070515 Firefox/2.0.0.4
Accept: 
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
Accept-Language: es-es,es;q=0.8,ca;q=0.6,en;q=0.4,de;q=0.2
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive
Cache-Control: no-cache
--
this is the response (error 404):
--
HTTP/1.x 404 /herramientas/sincronizar1.jnlp
Date: Wed, 04 Jul 2007 15:44:39 GMT
Server: Apache

Content-Length: 1683
Keep-Alive: timeout=15, max=100

--

But, with this rewrite rule (html):
--
RewriteBase /herramientas/
RewriteRule ^sincronizar1\.html$ sincronizar.php
--
and this request:
--
GET /herramientas/sincronizar1.html HTTP/1.1
Host: www.electrodh.com
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; es-ES; rv:1.8.1.4) 
Gecko/20070515 Firefox/2.0.0.4
Accept: 
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
Accept-Language: es-es,es;q=0.8,ca;q=0.6,en;q=0.4,de;q=0.2
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive
Cache-Control: no-cache
--
this is the response:
--
HTTP/1.x 200 OK
Date: Wed, 04 Jul 2007 15:51:38 GMT
Server: Apache
Expires: 0
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/x-java-jnlp-file
X-Antivirus: avast! 4
X-Antivirus-Status: Clean
--

So, *.html urls are rewriten, but *.jnlp urls aren't.
