You don't need to create multiple helpers (you can, but there is no real need. You can simply alternate "SetContentStore"/"Install" with normal and null (nocache) CS.</div><div><br></div><div>CS is very powerful component of NDN system, but its absence does not prevent communication.</div><div><br></div><div>---</div><div>Alex</div><div><br></div><div><br></div><br><blockquote type="cite"><div lang="FR" link="blue" vlink="purple" style="font-family: Menlo-Regular; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US">thx<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US"> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;"><span style="font-size: 12pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);">Nour El Houda Ben Youssef Koubaa<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;"><span style="font-size: 12pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);">Doctorante Mobidoc - OXIA/SAGE<br>Mastère nouvelle génération des systèmes d'informations - FST<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;"><span style="font-size: 12pt; font-family: Arial, sans-serif; color: rgb(34, 34, 34);">Ingénieur Génie Logiciel - INSAT</span></div></div></div></blockquote></div><br></body></html>
