IIS Rewrite rule, url modify himself - iis

Question

I have write a rewrite rule to redirect an incoming request to the correct server.
Here my web.config :
<rules>
<rule name="ToMonceau">
<match url="test/(.*)" />
<action type="Rewrite" url="http://10.5.5.83/{R:1}" />
<serverVariables>
<set name="HTTP_X_ORIGINAL_ACCEPT_ENCODING" value="{HTTP_ACCEPT_ENCODING}" />
<set name="HTTP_ACCEPT_ENCODING" value="" />
</serverVariables>
</rule>
</rules>
<outboundRules>
<rule name="AddPrefix" preCondition="IsText" enabled="true">
<match filterByTags="A, Img, Link, Script" pattern="(http://10.5.5.83/mantis/)?(/mantis/)?(.*)" />
<conditions>
<add input="{URL}" pattern="(test/mantis)/(.*)" />
</conditions>
<action type="Rewrite" value="./{R:3}" />
</rule>
<rule name="RestoreAcceptEncofing" preCondition="NeedsRestoringAcceptEncoding">
<match serverVariable="HTTP_ACCEPT_ENCODING" pattern="^(.*)" />
<action type="Rewrite" value="{HTTP_X_ORIGINAL_ACCEPT_ENCODING}" />
</rule>
<preConditions>
<preCondition name="IsText">
<add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/(.+)" />
</preCondition>
<preCondition name="NeedsRestoringAcceptEncoding">
<add input="{HTTP_X_ORIGINAL_ACCEPT_ENCODING}" pattern=".*" />
</preCondition>
</preConditions>
</outboundRules>
My problem when I go to http://localhost/test/mantis (my server hosts a mantis here), the url change automatically to http://localhost/mantis/, I have to put again the "test/" and it change to http://localhost/mantis/login_page.php. I reput again "test/" and this time the login's page of mantis shown.
The problem continue when I try to log in, the url changes continously by removing the "test/" part.
If I go directly to my mantis without the redirect (http://10.5.5.83/mantis) everything is working like a charm.
What am I missing in my rule to do it correctly ?
I take the exemple here with mantis but I have the same problem on every sites host by different server.
Thanks in advance and sorry if my english is not perfect.

Go to IIS manager and click on URL rewrite:
Keep pattern .*
Action type should be Rewrite
Rewrite URL: http://yourdesiredurl/{R:0}
