Let's say I have the following URL addresses:

```
www.mydomain.com/default.aspx?param1=value1&param2=value2&param3=value3
OR
www.mydomain.com/default.aspx?param2=value2&param1=value1
OR
www.mydomain.com/default.aspx?param3=value3&param1=value1&param2=value2

```

How can I remove only the part "param1=value1" from those URL addresses with jQuery or Javascript?
