I`m planning to build new One Time URL script, after i found that the old version is bit problematic, i start to planning Advance One Time URL script.
- using mySql as db.
- make one time url and store it in db.
- option to make few times url with limit.
- using http headers to force download – and not redirect as old script.
- mod_rewrite mode.
- regular link mode.
- install script – build the mySql schema.
- custom redirection for expired links.
- config file (db params, redirection params, default mode, etc…).
If you have more ideas, you can write it as comment.
