proxypass from another host - type 'exceptions.TypeError'

Hello,

We're trying to use the openerp webclient in this schema :

[Proxy server - Apache]
       |
[Openerp server - with openerp webclient]

Apache configuration on proxy :

<Proxy http://openerp-srv1.toto.com:8080/*>
  Order deny,allow
  Allow from all
</Proxy>

RewriteEngine On

RewriteCond %{HTTP_HOST} ^demo.titi.com$
RewriteCond %{HTTPS} off
RewriteRule ^/(.*)$ https://demo.titi.com/ [L]

RewriteCond %{HTTP_HOST} ^demo.titi.com$
RewriteRule ^/(.*)$ http://openerp-srv1.toto.com:8080/$1 [P,L]

Configuration for webclient on openerp-srv1 :

[global]
server.socket_host = "0.0.0.0"
server.socket_port = 8080
server.thread_pool = 10
server.environment = "development"
server.profile_on = False
server.profile_dir = "profile"

tools.proxy.on = True
#tools.proxy.base = '''

log.access_file = "/var/log/openerp-web/access.log"
log.error_file = "/var/log/openerp-web/error.log"

[openerp]
host = 'localhost'
port = '8070'
protocol = 'socket'

[openerp-web]
dblist.filter = 'EXACT'
dbbutton.visible = True
company.url = ''
child.listgrid.limit = 5
child.listgrid.min_rows = 5

What happens :

- We can log in, logout
- We can browse datas

- We CANNOT save anything. For example, when we modify a user's password, we have this error :

<type 'exceptions.TypeError'> Python 2.5.2: /usr/bin/python

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

<type 'exceptions.TypeError'>: index() got an unexpected keyword argument 'count'
      args = ("index() got an unexpected keyword argument 'count'",)
      message = "index() got an unexpected keyword argument 'count'"

What we tried :

- Disable tools.proxy.on : we cannot log out nor save stuff, we're redirected to the wrong server.
- Put an apache on openerp-srv1 with a simple proxypass, and setting up proxypass on demo.titi.com so that it uses apache on srv1. No chance - still crashing (same error).

We have seen that it seems to be the tools.proxy.on which causes this problem - deactivating it makes all work, except we're redirected to the wrong server while doing some stuff like logout, saving and so on....

NOTA: we cannot use tools.proxy.base, as we'll have many sub-domains (demo, client1, client2 and so on).

Any idea on how to correct it ?

Thanks in advance.

Best regards,

C.
