I run a website with a Google Maps on there on which I draw custom tile images with the help of RMagick. To give a pleasant and responsive user experience I supply minimal position data through a cookie with the tiles and have local JavaScript pick it up, digest it and act on it when the mouse is moved on the map. This works great as long as the items on 1 tile remains minimal. Whenever the item data in the cookie grows over 3KB (4KB escaped) I split it into several cookies. Internet Explorer 7 was patched last year to now accept 50 instead of 20 cookies per domain, yet the hardest limit of 4KB for ALL COOKIES in the document still remains. Is there a way to make it happen that the limit of 4KB only applies to a single cookie? Like FireFox handles it? Or do I have to resort to alternative measures involving an extra call to the server. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I know cookies aren''t there for what I wanted to do. It is a great way to serve meta data with the image tiles at the same time though. Since Google Maps API handles all the requests for the tile, there is no way to come inbetween there to fill some div with my JS data like you suggested. If you have a practical example I''d be very glad to see it. The data for each tile is very specific and based on several parameters hashed to a tile name. So indexing by Google is unwanted even. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you have a practical example I''d be very glad to see it.Unless I''m totally wrong on what you''re trying to do, here''s some pseudocode on how I see it: <ul id="positional-data"> <li><em>37.4419, -122.1419</em><div class="content">put any content for your marker here</div> <li><em>38.4523, -121.1887</em><div class="content">put other content here</div> </ul> Javascript pseudocode (won''t work, but you get the picture): $(''positional-data'').select(''li).each(function(el) { new GMarker(new google.maps.LatLng(el.down(''em'').innerHTML), el.down(''.content'')); }); Best regards Peter De Berdt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
