Hi again,
I use virtual directories since yaws 1.77 by using the the arg_rewrite function from the old yaws_vdir module.
This module is no more provided in the yaws releases. And the vdir example in documentation always use it.
Again, I missing something ?
thank you

I think you are - the vdir feature was added quite some time ago, however it's poorly
documented.
The yaws.conf man page says:
Finally an example with virtual directories, vdirs.
<server server.domain>
port = 80
listen = 192.168.128.31
docroot = /var/yaws/www
arg_rewrite_mod = yaws_vdir
<opaque>
vdir = "/virtual1/ /usr/local/somewhere/notrelated/to/main/docroot"
vdir = "/myapp/ /some/other/path can include/spaces"
vdir = "/icons/ /usr/local/www/yaws/icons"
</opaque>
</server>
The first defined vdir can then be accessed at or under
http://server.domain/virtual1/ or http://server.domain/virtual1
AFAIK, that is all you need to do, the yaws_vdir module was removed long ago.

Which docs ?

mmm I don't understand,
If the configuration you set the arg_rewrite_mod to "yaws_vdir" but if this module does not exist how can that work ?

I think that in the initial, absolutely first attempts at implementing
vdirs, the guy who did that work - Julian Noble - first had it implemented
as an arg_rewite module (called yaws_vdir), but it was later changed to be
become entirely integrated into yaws_server.erl
?

so I tried this :
docroot is in /tmp/www
xen:/tmp# mkdir www
xen:/tmp# echo "welcome home" > www/index.html
xen:/tmp# mkdir www/test
xen:/tmp# echo "welcome test" > www/test/index.html
-------------------
TEST 1 :
Yaws configuration is :
<server localhost>
port = 8081
listen = 0.0.0.0
docroot = /tmp/www
dir_listings = false
statistics = true
arg_rewrite_mod = yaws_vdir
<opaque>
vdir = "/virtual/ /tmp/www/test/"
</opaque>
</server>
RESULT 1 :
=ERROR REPORT==== 21-Dec-2009::16:02:49 ===
Yaws process died: {undef,
[{yaws_vdir,arg_rewrite,
[{arg,#Port<0.955>,
{{192,168,1,2},1569},
{headers,"keep-alive",
"text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5",
Normal yaws_vdir does not exist ! :+) (It's the original reason of my post)
-----------------------------
TEST 2
Yaws configuration is :
<server localhost>
port = 8081
listen = 0.0.0.0
docroot = /tmp/www
dir_listings = false
statistics = true
<opaque>
vdir = "/virtual/ /tmp/www/test/"
</opaque>
</server>
Try a request on "/" :
=> "welcome home"
OK !
Try a request on "/test" :
=> "welcom test"
OK !
Try a request on "/virtual" :
Not Found
The requested URL /virtual was not found on this server.
NOK !
Try a request on "/virtual/" :
Not Found
The requested URL /virtual/ was not found on this server.
NOK !
Try a request on "/virtual/index.html" :
Not Found
The requested URL /virtual/ was not found on this server.
NOK !
---------------------------------------
yaws_server source code :
vdirpath/3 find the longest virtual path based on opaque configuration
vdirpath/3 is called by two functions :
-> ssi/6 : not concerned
-> mappath/3 : more interesting
And mappath is called by yaws_cgi module only.
So I have two solutions :
-> I become crazy
-> I try to use symlinks !!!! Even if I a request on the symlink do an I/O on inodes table. Yaws file caching system should limit this.

Sigh - I'm an idiot. (Ughhh, that hurt)
I removed the yaws_vdir.erl modules some time ago, I though it
was not needed any more - I was wrong.
Anyway, It last appeared in 1.84 (I attach the source here, you
can just drop it in the src directory)

no problem, but I conclude that I am the only one to use virtual directories :+)
your proposition to use symlinks sounds good, in fact I don't want to add too much overhead
thank you for your time

I guess you conclude rightly ...

Maybe not..
I recall that I had to do some fixes for the yapp handler (Yaws APPlications) when vdirs were introduced. These changes are still in place, although not using the yaws_vdirs module directly. Since yapps still seem to work I guess yaws_server is still handling the {"vdir",..} tuple.
Snippet from arg_rewrite in yapp.erl which rewrites the docroot:

Ok - thanks, all the more reason to have a deep look at the vdir feature.
