[us...@httpd] rewrite rule tutorial on ask apache I could not understand syntax
http://http://www.askapache.com/htaccess/crazy-advanced-mod_rewrite-tutorial.html
is a link to a tutorial which mentions following use of ReWriteRule is wrong.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]
RewriteRule .+ http://www.askapache.com%{REQUEST_URI}
I could not understand what is the mistake in the above rule?
Can some one point what is the error which the tutorial is trying to tell.

I don't know what he's smoking, I use a rule almost identical to that
in many places.
Perhaps it behaves differently in .htaccess configuration, which is
what he is describing.
The rule I use on a daily basis:
RewriteCond %{HTTP_HOST} !^(altname\.example\.com|name\.example\.com)$
RewriteRule ^/(.*) http://name.example.com/$1 [R=301,L]
Also, his point about not being able to see what the various variables
are, I kind of see his point, it would be nice to have examples of
what the variables could be, but you can always turn on the rewrite
log to see stuff like that.
Cheers
Tom

Who can guess if that silly page meant either of these subtle issues
with the recipe:
*) ".+" in .htaccess won't match a request for "/", but I doubt that's
the operative part of the exercise.
*) You Should not redirect if HTTP_HOST is empty, for HTTP/1.0
clients, or you might loop.

HTTP_HOST is a variable that holds the value of the http header 'Host'. If the browser doesn't send one, it isn't going to have a value.

Apache reads that header in and stores it on the request. mod_rewrite makes that variable available to read with the name HTTP_HOST. If the request is a HTTP/1.0 request, no host header is sent, so HTTP_HOST will be empty if examined. I can't explain the HTTP protocol + Apache on a mailing list. Do what I did and read RFC 2616 to understand HTTP, and read "Apache modules with Perl and C" to understand Apache (although it is a little dated now, it has an excellent section on the request life cycle).

[us...@httpd] Apache getting stuck with all workers in a BUSY_READ state
Hi, I've been having problems with apache becoming unresponsive, and was wondering if anyone had any suggestions on what the problem might be. Basically, periodically, apache will get into a state where all the workers are stuck reading: Server Version: Apache Server Built: Oct 21 2009 10:54:43 Current Time: Tuesday, 15-Jun-2010 07:57:30 PDT Restart Time: Tuesday, 15-Jun-2010 06:37:33 PDT Parent Server Generation: 0 Server uptime: 1 hour 19 minutes 57 seconds Total accesses: 985801 - Total Traffic: 8.1 GB CPU Usage: u644.89 s203.76 cu3994.75 cs0 - 101% CPU load 206 requests/sec - 1.7 MB/second - 8.6 kB/request 1593 requests currently being processed, 15 idle workers RCKRRRKR CRRR RRCK KRRR RRCR RKRR RRCRRKRRRKRK RRRK RKRR RRRKRKRR RWRR RRRWKKCRRKRKKRRC RRKK RRKR CKCCRRKRRRKRRRCRCCRRRCRRCRRR RRRKKRRWRKRRRKRW KKRRRKWRKRRRW___RRR__RR___R_ WRR__RRRSS.. This is prior to complete failure - sometimes whatever's blocking gets unblocked before it hits max clients, sometimes it doesn't. I'm running apache 2.0.59 built with openssl 0.9.8n on AIX 6.1 with prefork, and this is virtually all SSL traffic (pretty much everything other than the scoreboard). A restart basically "fixes" the problem, from the perspective that all the workers get killed and after the initial thrashing of starting up new workers. >From my understanding of the READ state above, everything above is stuck in one of two broad categories: - A client made the TCP connection to the server, and is somewhere between the tcp handshake and the end of the HTTP Request info. This suggests it could be a network issue (something's hanging the connections), or an openssl issue (the TLS/SSL negotiation is slow/hanging), or...? - The request has been completed, but we're proxying to somewhere else and waiting for a response from the proxy. This potentially applies in this case, because we do have apache setup to proxy some URLs to another server. There's nothing in the access or error logs jumping out to correlate with this problem either - There are MaxClient issues once it hits that, of course, but nothing related to the BUSY_READ state. When having the problem, I've correlated the scoreboard with the ps/lsof/netstat output, and the second case seems unlikely because I'm not seeing any open connections to the server that apache is proxy'ing to. It feels like there's some shared resource that all the apache workers are trying to access, but I can't figure out what it might be. Any suggestions on a solution, or how I might get more info out of apache as to what it's doing while everyone's in the read state? Are there other broad categories I'm missing as to why the workers might be in the read state? Any further info I could provide to help anyone? My next steps are to dive into the apache source further and see what possible resources it could be blocking on, but I'm hoping someone smarter than me already knows. :) -- Dave Fallon - The official User-To-User support forum of the Apache HTTP Server Project.

[us...@httpd] I/O accounting for all processes?
Hi to all. I'm interested in measuring I/O that all apache processes are generating. Is that possible somehow? I know that on Linux, after 2.6.28 there is I/O accounting per PID, but that's not satisfying for me because apache PIDs in prefork mode change and are not the same... I need this to calculate I/O needed for my load balancing cluster.

[us...@httpd] mod_nss + OCSP configuration problem

I changed the nss.conf to have the following configuration NSSCertificateDatabase /usr/local/apache/nss NSSVerifyClient require NSSOCSP on NSSOCSPDefaultResponder on NSSOCSPDefaultURL http://myip:3456 NSSOCSPDefaultName my_ocsp I have a openssl OCSP server running like this openssl ocsp -index index.txt -CA cacert.pem -rsigner cacert.pem -rkey private/cakey.pem -port 3456 But when i start the Apache httpd server, I see the following error: Certificate not verified: 'Server-Cert' SSL Library Error: -8063 The response from the OCSP server was corrupted or improperly formed. I am new to OCSP and would really appreciate any help on this. Thanks in advance. Thanks & Regards, Aruna.

I would try using strace (or ktrace or truss depending on your OS) on the processes to see what they are doing. Between that and lsof you should be able to tell what the process is blocked reading. Hope this is helpful, Scott.
