ZOMDir's logo

I always state that ZOMDir's logo is a salamander, which is based on Escher's reptiles. Recently I discovered that a Gecko is a reptile and a Salamander is an amphibian. I think I need to update my biology knowledge ;-)

I also discovered that Gecko is a layout engine used by the Mozilla Foundation and the Mozzilla Corporation. That is funny because the Open Directory Project (dmoz.org) was originally named: Directory MOZilla.

ZOMDir is named ZOMDir because I wanted to re-invent DMOZ, reverse the bold letters and you have ZOMDir. Despite that it is pure coincidence that the salamander is used as logo for ZOMDir.

HTTP Errors

Since the launch of ZOMDir at June 5, 2013 I add a regular base sites myself to the directory. This is great for discovering small "bugs".

In the past a time-out of 7 seconds, before the conclusion is drawn that the given site isn't responding. I discovered that a time-out of 12 seconds is better. Some sites are really slow ...

I also discovered that there are websites which show up in the browser. However when I try to fetch these websites, I get the result "None" and a HTTP error (code 403 and code 412). Very strange indeed.

According to the Hypertext Transfer Protocol these codes have the following meaning:

403 Forbidden
The request was a valid request, but the server is refusing to respond to it.

412 Precondition Failed
The server does not meet one of the preconditions that the requester put on the request.

I really don't understand why browsers correctly shows these websites and while ZOMDir is not able to fetch them correctly.

If you have a clue, please let me know.

Thanks,

Hans

Note: Recently I found a website with the status 300 Multiple choices. That one is also difficult to handle.
