It is somewhat related to lwIP as you have to know how to create dynamic 
content. That depends on the webserver.

Yes. If you use lwip's integrated httpd, that is.

You can use SSI to generate the different links. In the lwIP http 
server, SSI works everywhere in the page, even in a form or in a link 
element. You only have to set LWIP_HTTPD_SSI_INCLUDE_TAG to 0. If this 
is 1, the tag part of the html source file gets included in the 
resulting page and that might violate the html code.
