";" semi-colons in urls

[1/8] from: norsepower:uswest at: 10-Jan-2001 23:33

Using 'read or 'browse on the following url brings up an error page, but dropping the same url in a browser address bar loads the page ok. Is there something about this url construction which REBOL can't handle? (I see the semi-colons may pose a problem?) http://ad2.doubleclick.net/jump/sonar.bebits/default;sz=468x60;ord=979190170 -Ryan

The semicolon introduces comments in REBOL, i.e. the scanner considers ;sz=468x60;ord=979190170 to be a comment in your script and does not include it in the URL. Workarounds: Either: to-url "http://ad2.doubleclick.net/jump/sonar.bebits/default;sz=468x60;ord=979190170" Or: http://ad2.doubleclick.net/jump/sonar.bebits/default%3Bsz=468x60%3Bord=979190170 %3B is the hex representation of the ASCII code of ";". -- Holger Kruse [holger--rebol--com]

Either I didn't understand your solution or it doesn't work with REBOL/Core 2.3.0.3.1 for Windows.

190170 == http://ad2.doubleclick.net/jump/sonar.bebits/default This cuts off everything past the semi-colon

I also tried 'make 'url! with the same results. -Ryan

The URL should've been in quotes - ie a string. All the to-something words, (to-url, to-string etc.), are for forcing a value to be a specific datatype, even though they may be of another type. That said, I still get the same error as you.

Ok, looks like the version of REBOL you use still has the old URL parser, which does not support ";". Here is a workaround: http://ad2.doubleclick.net/jump/sonar.bebits/default%253Bsz=468x60%253Bord=979190170 This double-escapes the ";". The server should still be able to handle it. -- Holger Kruse [holger--rebol--com]

Is the new URL parser in an unreleased version of /Core? I tried to read or browse urls with ";" semi-colons in /Core (Experimental) 2.4.39.3.1 for Windows and the URLs do not work there, either.

This workaround does work, by the way. (Thank you.) The URL in the previous examples will no longer work (expired.) Here is a current URL that should work for anyone that wants to test it: http://ad2.doubleclick.net/click%253B929250%253B0-0%253B0%253B4336617%253B1-468|60%253B0|0|0%253B%253B%3fhttp://www.drugfreeamerica.org

Yes, it is a very recent change. Probably not in the current experimental... -- Holger Kruse [holger--rebol--com]
