I currently have /a1234 (any number after letter "a") rewriting to page.php?var=1234,
I have 1 particular page with number 55 I need to redirect elswehere.

```
rewriterule ^a55 /home/public_html/otherpage.php

```

While this simple line works, it also redirects /a555, /a5555 etc... to otherpage.php

* How do I only have it redirect just 55 and not 555 etc. ?
