jsf 2 - how to include only part of request params into url? -


i'm passing 2 parameters through h:link this:

<h:link outcome="index" value="index" >    <f:param name="a" value="#{bean.a}"  />    <f:param name="b" value="#{bean.b}"  /> </h:link>

in case both params shown in url. how can achieve param a , not b shown in url? thanks

if want 1 param shown in url, need pass one. get request(because link), can't restrict parameters being shown in url

<h:link outcome="index" value="index" >    <f:param name="a" value="#{bean.a}"  /> </h:link>
