I was tryig to learn .htaccess, and and had a question regarding this, i have asked the question here
Have I correctly pasted the question on pro webmaster or I should do it here on stackoverflow?
sorry, but i am much confused as htaccess tag is present at both locations. Sorry again if i have broke some rule
You’ve got the 500 because the syntax is wrong. It should be
$1.php. $a is not a valid variable.I’ve moved this to an answer, so you can mark it as resolved.
