String streamContents: [:stream | url do: [:each | (WAUrlEncoder encode: each on: stream)]] It just encodes on character at a time. Which gives you an identical answer up until _k, where I notice that Seaside doesn't encode _'s like your examples do, but I believe Seaside is correct here, _'s don't need encoding.

After two hours I have found what I was looking for: String>>> encodeForHTTP encodes the whole string: xmlUrl := xmlUrl encodeForHTTP. But it does not encode all (just like Seaside), it does not encode the '_' and the '.' as you can see from this result: xmlPath%3Dhttp%3A%2F%2Fwww.macmerik.nl%3A9090%2Fseaside%2Ftests% 2Ffacade%3F14%26_k%3DzllSchmY%26_s%3DqzSqkxyQfMWoNLdV So I will rewrite it to encode those characters as well, like the tool at http://www.dommermuth-1.com/protosite/experiments/encode/ index.html . This tool is written in Flash and does encode the '_' and '.' also. I need the conversion Flash uses because it is for passing url's with FlashVars to Flash. The question that remains is why some characters are not encoded and others are.

URL or in HTTP and they both fall within the 7 bit ASCII character set as standard printable characters. Encoding them would produce a needlessly long URL and waste CPU cycles at both ends. >From the RFC you quoted above: Thus, only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.

Flashvars is not documented so this is how you must find out. I have it running and implemented a special encodeForHTTPandFlashVars >> From your examples it's apparent that you don't want _every_ >> character > encoded as you're not expecting the standard alpha-numeric characters > to be encoded, so why underscore and full-stop? Again, it must be so as the tests prove. Merik _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

In reply to this post by Merik Voswinkel
Really? I use existing encoding to pass URLs to Flash components via vars and never noticed needing to change encoding to include underscore and period chars as it worked just fine so far. _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |
