A Link Between Internal Documents Uses A Relative Url

We can distinguish between absolute, path and relative links.

Absolute Links

Pros:

  • increase number of entries in cache, bloats cache
  • beneficial for search engine optimization
  • allows for dedicated zope "threading" of resources by domain

Cons:

  • incompatible with restricted site access
  • reduces portability from one website to another

Path Links

Pros:

  • minimizes number of entries in cache
  • compatible with restricted access on one site
  • ensures content portability from one website to another

Cons:

  • disadvantageous for zope "threading" resource utilization per domain
  • inferior for search engine optimization

Relative Links

Pros:

  • minimizes number of entries in cache
  • compatible with restricted access on one site
  • ensures content portability from one website to another

Cons:

  • reduces ability to cache
  • inferior for search engine optimization
  • disadvantageous for zope "threading" resource utilization per domain

Because we favour security and content portability, links from one HTML content to another HTML content should be relative link except link to content that only makes sense in a given context, for example an absolute lnk for a Nexedi press release which should be displayed on a Nexedi website.

Good Example:

Bad Examples:
