scope= "request" in structs-config.xml

[Sreejith kayappuram]

hi,
One of my jsp form's text field shows previously entered values even when i reload the form after loading other jsps. I have overrided reset method of form bean and hence each time i load the jsp, the form bean contains only null values ( like name field will be set to null in reset method) but the jsp's corresponding text field shows previouly entered values...
it got corrected when i change

<action path="/prepareuser"
type="com.security.ManageUserAction"
name="UserSearchForm"
validate="false"
scope="request">
<forward name="success" path="usersearch.do" />
</action>

by removing the scope="request" entry

<action path="/prepareuser"
type="com.security.ManageUserAction"
name="UserSearchForm"
validate="false"
>
<forward name="success" path="usersearch.do" />
</action>


could any body please tell me whats the purpose of scope= "request" in structs-config.xml
