asp.net mvc 4 - preventing refresh when clicking on the current page -


i'm new asp.net mvc4.

i'm implementing navigation bar in website.

i'd prevent refresh when clicking current page in nav bar.

update i'm using razor navigation bar:

<ul>  @html.actionlink("feature_1_url","feature_1_url","home") @html.actionlink("feature_2_url","feature_2_url","home") @html.actionlink("feature_4_url","feature_4_url","home") </ul>

how can accomplish it?

in given solutions page refreshed reduce server call , not call action again , again.

in mvc4 1 of best way can achieve purpose using caching 

[outputcache(duration=30)] public actionresult feature_1_url(){}

so specifying time store result in caching when click next time actionlink give result caching data per duration time , reduce request server.

this can useful @ least fast response
