Daniel,

I did have the same results than you. Whatever the encapsultation used
for html files: Directory or Files... For these tests I'm using 2
Solaris 8 boxes running the latest greatest Apache 1.3 + backhand.
The candidacy funtions used are so simple...:

backhand byAge
backhand byRandom

http://www.website.com/test.html will work perfectly
http://www.website.com/index.html will generate random file not found
http://www.website.com/ will generate random file not found

It is interesting to observe that using the byLoad function decrease the
number of "File not found" produced. E.g:

backhand byAge
backhand byRandom
backhand byLoad

Under the assumption that two frontier servers were may be not
sufficient, we used a slightly different configuration, adding a 3rd
servers. AS far as I remember the configuration was based on 1 frontier
server and 2 backends. All the HTTP requests were directed to the
frontier. The frontier server was load balancing the requests to the two
backend servers with the followind conf:

backhand byAge
backhand byRandom

And the random file not found never appeared.

Any idea?

Lionel Raynaud.

I have this too -- I would love to figure out why so I can take those
"Backhand off" rules out of the config for default files!

Can you explain your setup? I'm wondering if one of your machines is
out of sync. I bet there's one machine in your cluster that's
generating the 404's and because you're using byRandom, it looks like
random 404's. -sc

It's definitely my second server that is causing it ... I have a www1 that
has the external interface, as well as www2 that is connected to www1 via
private network.

taking about byRandom seems to have worked


my set up is two debian woody machines, so both have the same version of
apache/backhand
two machiness total. I don't get any 404 errors on the second machine.
This is even under extremely light load.

Using ab with 1000 requests 30 at a time
300 to first machine work fine
200 to second machine work fine
500 404 errors on first machine

<IfModule mod_backhand.c>
UnixSocketDir /var/run/libapache-mod-backhand
MulticastStats 225.220.221.20:4445,1
AcceptStats 216.133.246.64/27
</IfModule>

<VirualHost ip>
<FilesMatch "\.php$">
Backhand byBusyChildren
Backhand byRandom
</FilesMatch>
</VirtualHost>

I am having sligtly different behaviour in that request to index.php
work fine:
http://www.website.com/test.php will work perfectly
http://www.website.com/index.php will work perfectly
http://www.website.com/ will generate file not found


I changed the FileMatch setup to
<FilesMatch "\.php$">
Backhand byBusyChildren
Backhand byLoad
</FilesMatch>

and the errors went away - ab reports 0 404 errors.

why is byRandom sending requests to /index.php instead of
/path/to/www/index.php?

it seems to have worked for me.

Hmmm... put back in byRandom and add removeSelf before byRandom and
see if that fixes things. -sc

--
Sean Chittenden

this produces lots of errors:
<FilesMatch "\.php$">
Backhand byBusyChildren
Backhand byRandom
</FilesMatch>

this produced no errors:
<FilesMatch "\.php$">
Backhand byBusyChildren
Backhand removeSelf
Backhand byRandom
</FilesMatch>

Probably because Self didn't have the file...

Because you're no longer requesting to the machine that's doing the
proxying. :~) -sc

Sean Chittenden

self does have the file.
there are only two machines, and both of them have all the files.

the apache log says the request is going to
/index.php
instead of
/path/to/www/index.php

apache should NEVER be sending requests to
/index.php

Apache will only log URI, not the full path to the file. Is
/path/to/www/ your document root? -sc
