Introduction

Logiweb relays provide two services: Firstly, they resolve Logiweb references into http indirections so that one can effectively reference a Logiweb page from the World Wide Web. Secondly, they allow advanced users to experiment with the Logiweb protocol in that they provide a user interface for sending Logiweb messages to Logiweb servers and receiving the associated responses.

Resolving references

To resolve a Logiweb reference via a Logiweb relay, look up relay-name/go/reference.

relay-name could be something like http://logiweb.eu/logiweb/server/relay.

reference must be a Logiweb reference expressed in mixed endian hexadecimal. Alternatively, one may replace 'go' by '32' or '64' and express the reference base 32 or base 64.

Looking up relay-name/go/reference results in an html page that redirects your browser to the Logiweb page. Your browser will then typically ask you what to do with a page of type application/x-logiweb.

If you look up relay-name/go/reference/level/path instead, then the relay will first resolve relay-name/go/reference into an url, then, if e.g. level=2, redirect to ../../path relative to that url. The level indicates the number of ../ to prepend the relative path.

As an example, if 01...06 is a Logiweb reference in mixed endian notation (the elipsis represents about 60 hex digits) then http://logiweb.eu/logiweb/server/relay/go/01...06 looks up the Logiweb page with reference 01...06 and http://logiweb.eu/logiweb/server/relay/go/01...06/2/body/tex/page.pdf looks up ../../body/tex/page.pdf relative to the Logiweb page. The crossbrowser places the TeX/PDF face of the page at exactly that location.

Sending messages

To send a message to a Logiweb server via a Logiweb relay, look up relay-name/hex/request.

relay-name could be something like http://logiweb.eu/logiweb/server/relay.

request must be a Logiweb request expressed in mixed endian hexadecimal.

Looking up relay-name/hex/request results in an html page that comments on the request and the associated response (if any).
