For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Passing GET parameters through Apache mod_rewrite

If you're using Apache mod_rewrite to redirect a series of URLs to a single script, did you know that you can pass values entered onto a form via the GET method through as well? Simply add on %{QUERY_STRING} onto the end of your new URL. You'll need to add a ? into the target URL to ensure that the query string is taken as such .... and you can even add more parameters if you wish.

Here's how we divert all requests to .htm, .html, .php, .php4 and .php5 files in a directory to a single script called b.php; we pass in any parameters the user filled in on his web page, and we generate an extra request parameter called pagename that contains ... of course ... the name of the page requested.

RewriteEngine On
RewriteRule ^(.*)\.htm b.php?pagename=$1&%{QUERY_STRING}
RewriteRule ^(.*)\.php b.php?pagename=$1&%{QUERY_STRING}

Anonymous:I just got the contents of your blog as spam. Presumably they put it in to get past filters. Then they attached a "stock tip" (the spam payload) as a GIF.

graham Ellis:Thanks, 'Anon' .... it's published on the web so I guess anyone can illicitly copy and paste it; not much I can do about that. Just one step further than simply ripping of someone's email address. Constructive suggestions welcomed ...
