[users@httpd] mod rewrite question https to http
Dear all,
I'm a complete newbie to apache and i've inherited a virtual host setup.i have
the need to redirect all traffic from https to http (443 to 80, yes that is
correct)
the relevant rewrite rules in httpd.conf are as such:
# all other traffic is redirected to the SSL siteRewriteEngine On
RewriteRule ^/cgi-bin/u/testing.cgi - [L]RewriteRule ^/cgi-bin/voice - [L]
RewriteRule ^/cgi-bin/testing2.cgi - [L]RewriteRule
^/cgi-bin/u/results.pl - [L]RewriteRule ^/audio - [L] RewriteRule ^/gram
- [L] RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [L,R=301]
Any advice on how to force all https links to be redirected to http ?
Thanks in advance
[users@httpd] Experiencing odd, possibly JPEG-specific slowdowns
I'm in the process of moving a domain from a virtual host on a physical box (CentOS 5.5, Apache 2.0.6.3) to a virtual host on a VPS (CentOS 6.2, Apache 2.2.21). The two machines (one physical, one virtual) should have broadly similar performance and memory availability; the physical box is more heavily-loaded, and hosts vastly more sites. The VPS is essentially idling. The old domain is hosted by my ISP, so I don't have information about the options used to build the Apache, or the httpd.conf that it uses. The Apache on the new box was built with the prefork MPM, and the httpd.conf is almost unchanged from the standard default conf. I've turned on name-based virtual hosts and added some AddOutputFilterByType rules to direct compressible content (HTML, CSS etc, but not images) to mod_deflate, but that's about all. When I fetch pages from the new server using a web browser, it's noticeably slower than fetching the same content from the old server. There are two particular problem cases that I have seen. 1. HTML page with thumbnails When I fetch a simple static HTML page with a number of embedded thumbnails in it, there is frequently a noticeable delay before some of the thumbnails load from the new server. Looking at the graph in Firebug, I see that the initial HTML and CSS loads, we reach the DOMContentLoaded point, and then the browser goes into a long - almost one second - wait for the first three thumbnails. From the graph it seems that the browser is fetching six content items in parallel: 3 GIF images (200 bytes to 2.5K) download almost instantly, while the 3 JPEG images (1.7-2K) are held up for over a second. On the older server, this doesn't happen, or happens much less: everything seems to be delivered much more quickly, with only the last JPEG forced to wait for any length of time. 2. Isolated JPEG The second oddity occurs when I download a single unembedded JPEG image (84K) in my browser. On the new server, the image can take up to 14 seconds to download; on the older server, it consistently arrives in less then .5s. Firebug shows the bulk of the time being taken up by 'waiting'. The obvious suspicion would be that the old server is on a faster connection, but if I download the same image from the two servers using curl, the image actually downloads about 10% faster from the new server than the old one. As far as I can tell, the connection to my new server is actually faster. I'm testing using Firefox on a Mac simply because Firebug gives me pretty graphs, but I've been able to reproduce the same problem with other browsers, including Chrome, Raven, Internet Explorer on Windows 7, and even Mobile Safari on iOS 5. Very occasionally, I can get very slow transfers when testing with curl or libwww-Perl. I tried enabling 'sendfile' and 'mmap' on the new server but didn't notice any difference. Can anyone suggest what's going on here, and if there are any configuration settings that I could apply to try to make the new server perform as well as the older one?

RE: [users@httpd] Experiencing odd, possibly JPEG-specific slowdowns
Enable the %D in the logs - it will tell you how long the server takes to serve the query, in microseconds. It can be very long from client side but fast from server side - and even if slow from server side, it can be the client that hangs in the middle of the transaction (for very large ressources - not really your case). I had a similar problem - up to 120 seconds to serve some static resources, for around 0.5% of the queries. I wrote a script to test this (making thousands of requests and showing only the ones that are slow to match in the logs), even in local it took the same time - if interested let me know I'll send it to you. I'm still not able to tell why it behave that way, it disappeared (almost) when we moved from prefork to worker mode. All I saw was 2 or 3 occurences of 2sec for a small gif. -Original Message- From: Angus McIntyre [mailto:an...@pobox.com] Sent: Wednesday 1 February 2012 15:56 To: users@httpd.apache.org Subject: [users@httpd] Experiencing odd, possibly JPEG-specific slowdowns I'm in the process of moving a domain from a virtual host on a physical box (CentOS 5.5, Apache 2.0.6.3) to a virtual host on a VPS (CentOS 6.2, Apache 2.2.21).

Re: [users@httpd] How to make Apache mod_deflate and Transfer-encoding : Chunked work together?
Hi William, I have seen web sites forcing the chunked transfer-encoding as well as gzip content encoding. One of the biggest example is *facebook*. And *facebook*uses apache on linux. Please refer this link on progressive rendering using chunked transfer encoding. http://www.phpied.com/progressive-rendering-via-multiple-flushes/ If you search big pipe on web you will find plenty of references of using chunked transfer encoding. Also apache does allow chunking if I don't enable mod_deflate module. Old mod_gzip module which was packaged with old apache 1.3 had an directive specifically for not dechunking. * * *mod_gzip_dechunk No* So status right now is if i don't use compression on apache response is sent chunk by chunk.
