I have a Drupal 7 site and have a bunch of custom modules installed. Currently when I hit a specific node/9283 it gets redirected to another page. I'm not sure which module is causing this redirect. I also check URL Alias and nothing is there for redirection. Its definitely something custom. How would you go about debugging this and figuring out which module/code/function is being loaded on this redirect to another page on the same site?

What kind of redirect is it? HTTP status code? Which one? Or JS? Or meta http-equiv? Or something else? And you have php module turned off, right?– MołotCommented Oct 13, 2015 at 21:08

im not sure how you would find the http status code. i turned off JS and it still redirects. so something on the backend is firing.– Patoshi パトシCommented Oct 13, 2015 at 21:13

Use browser's console, network card? F12 in Chrome, for example? I don't want to sound mean, but that's kinda basic thing when developing and debugging interactions between server and client side.– MołotCommented Oct 13, 2015 at 21:15

If we're talking Drupal redirects (i.e. drupal_goto calls), the Devel module could help out here. In its settings it has a Display redirection page option that halts redirection for inspection.
You can use this in conjunction with a hook_drupal_goto_alter() invocation to dump a stack trace on the redirection halt page to find the origin of the drupal_goto call.
function MYMODULE_drupal_goto_alter(&$path, &$options, &$http_response_code) {
ddebug_backtrace();
}

What I do is:
Clone site do dev environment
Step by step execution
Simple, once you get your development environment up and running.

all these years. i have never setup xdebug before. i can't really clone the site that easily as its 30gb+... -_- .. i am working remotely off of the dev server. aside from xdebug how else would you debug this? Commented Oct 13, 2015 at 21:04

@duckx I usually omit media files when cloning - then 30GB shrinks to mere dozens of megabytes, usually. Aside from xdebug? I would try not to. Like, at all. Either it's my site and I know what I changed, or it's inherited and if it's owner does not want to provide infrastructure with dev environment, I don't want to work for him. But see my comment under your question.– MołotCommented Oct 13, 2015 at 21:08

i remember there was a way to do some type of back trace function finding thing by adding a function call in the index.php .. forgot how that was done. it was a long time ago. Commented Oct 13, 2015 at 21:14
