For edoornav,

at the configuration suggested by ZareMedia

application/config/config.php

I’ve added

.htaccess

this seems to enable mixed uri/qs urls without ‘index.php’ like

mysite.com/conroller/function/param?a=xx&b=yy

Sorry..
after some more tests I think that the better (more compatible) solution
to use url like:  mysite.com/conroller/function/param?a=xx&b=yy

is:

i.e. the OpenID standard uses get requests.

Sorry..
after some more tests I think that the better (more compatible) solution
to use url like:  mysite.com/conroller/function/param?a=xx&b=yy

is:

$config['index_page'] = "";
$config['uri_protocol']    = "AUTO";
$config['permitted_uri_chars'] = '';
$config['enable_query_strings'] = TRUE;

RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [QSA,L]

Unfortunately this didn’t work for me,
I get a server error so it must be something with .htaccess

Hmm… I’ve managed to get a system working whereby I can have URL’s like this:

All I had to do was extend CI’s input class (MY_Input.php):

And in my config.php

And it works fine!

Before I dig into the various number of solutions above I would just like to point out that it’s, or should be, considered a bug if a url fails because it has a parameter added to it. This isn’t normal web-behavior and can have unforseen effects, for example with Google Analytics and Google Adwords.

Example: http://www.example.com/blog/ is a blog that ends up being linked on some site. This sites forum-software adds a parameter to help you trace visits from them, making the url be:
http://www.example.com/blog/?referrel=somesite.com
suddenly your site returns 404 Page Not Found

It’s frankly very bad for sites…discarding it can be fine, but not error’ing out due to it.
