How can I write regex to redirect these links?

Question

Hi !
I am a novice who wants to re-direct certain links(which have similar names) to a single link using an addon that demands regex. I have been trying to learn regex quickly but so far have not succeeded. If you could please help me with this, I'd be grateful.

These are the sample links I want to redirect:
http://119.81.17.211/master/Check.aspx?enc=SHTQGW45UN0VM0MYU3YLIMBHQO
http://119.81.17.211/master/Check.aspx?enc=SHTQGW45UN0VM0MYU3YLIMBHMOM
http://119.81.17.211/master/Check.aspx?enc=SHTQGW45UN0VM0MYU3YLIMBHMXP

I want to redirect these to the following link:
http://4gp.tw/b025/1386177834502.pdf

Thanks a lot.

That regex should do it. It isn't elegant, but it should work. You might need to make the backslashes ( / ) literals with the forwardslash ( &#92; ), I can't remember if its a special character or not.

&#92;d - decimal number.
+ - one or more of the previous.
&#92;. - a literal period. Otherwise the period would be treated as the wildcard character and match anything.
