Re: URLConnection

GET-POST seems to be an issue here indeed. However,after adaptation
according to your suggestions, I still get a 500-error, from the W3C
site as well as my localhost.

Further below is the relevant piece of source code.

Firefox has this plug-in to invesxtigate HTTP data sent. this gives
the following when using the url :
http://jigsaw.w3.org/css-validator/validator?text=h2{margin-left:23px;}

the relevant piece of my source is this:
