A customer would like to have the headlines of articles used as URLs. The database field of the headline is a varchar(512), so in the worst case I would have
http://+domain with 19 chars+512 chars+.html
means 543 chars if I ignore the categories (which could be nested and theoretically be of endless length).
I read that on server-side there is a limit of 4000 chars, but there may be browsers which are limited to 256(!) chars. On which information can I rely?
