Housekeeping Issue

My housekeeping only works on this link,

http://habtown.co.uk/ase/index.php?url=chatlogs

When it should be

http://habtown.co.uk/ase/chatlogs

I have the web.config and it's all right. I don't know what the issue is!

PHP Code:

---

<rule name="Imported Rule 1">                    <match url="^(|/)$" ignoreCase="false" />                    <action type="Rewrite" url="index.php?url={R:1}" appendQueryString="false" />                </rule>                <rule name="Imported Rule 2">                    <match url="^([a-zA-Z0-9_-]+)(|/)$" ignoreCase="false" />                    <action type="Rewrite" url="index.php?url={R:1}" appendQueryString="false" />                </rule>                <rule name="Imported Rule 3">                    <match url="^(.*)\.htm$" />                    <action type="Rewrite" url="{R:1}.php" />                </rule>                <rule name="Imported Rule 4">                    <match url="^(|/)$" ignoreCase="false" />                    <action type="Rewrite" url="dash.php?page={R:1}" appendQueryString="false" />                </rule>                <rule name="Imported Rule 5">                    <match url="^([a-zA-Z0-9_-]+)(|/)$" ignoreCase="false" />                    <action type="Rewrite" url="dash.php?url={R:1}" appendQueryString="false" />                </rule>
