[webanywhere-dev] Why substitute "replace" with "rep" in wawp.php?

[Cameron Wong]

Hi Jeff,

In wawp.php, there is such line, which will make the javascript method
string.replace unusable. What's the purpose of this line? I would like
to comment it out. Thanks!

$_response_body = preg_replace('#\.replace\(([^\/])#is', '.rep($1',
$_response_body);

Hi Cameron,

This is a heuristic for getting rid of Javascript of the form
location.replace() which can cause WA to lose control of the page.

We'd obviously prefer a cleaner solution than this, but it sort of works.

Thanks,
Jeff
