RewriteRule for the same file which is currently targeted

I have a file like

www.domain.com/test.php

I want to write a rule that when ever this is called i am sending an argument to this file but I don't want them to show in the URL I.E. when the above path is in the browser the actual rule should be:

www.domain.com/test.php?state=yes

What should be the .htaccess rule for this? Currently i have in my .htaccess

RewriteCond %{HTTP_HOST} ^www\.domain\.com$  [NC]
RewriteRule ^test\.php$ /test.php?view=index [NC,L开发者_如何学Python]

But this is throwing a 500 server error???

I don't get a 500 error, what else do you have in your .htaccess?

Here's what you can use:

RewriteEngine on
RewriteBase /
RewriteRule ^test\.php test.php?view=index [NC,L,QSA]

The QSA flag was missing:

When the replacement URI contains a query string, the default behavior of RewriteRule is to discard the existing query string, and replace it with the newly generated one. Using the [QSA] flag causes the query strings to be combined.

Consider the following rule:

RewriteRule /pages/(.+) /page.php?page=$1 [QSA]

With the [QSA] flag, a request for /pages/123?one=two will be mapped to /page.php?page=123&one=two. Without the [QSA] flag, that same request will be mapped to /page.php?page=123 - that is, the existing query string will be discarded.
