global_bootstrap_init_start code causing 301 redirects

[sacobra]

I have got this the following code in global_bootstrap_init_start hook for Janrain plugin.

$engage_token = $vbulletin->input->clean_gpc('p', 'token', TYPE_STR); 
$engage_callback = $vbulletin->input->clean_gpc('g', 'engage_callback', TYPE_INT); 
$add_engage_identifier = $vbulletin->input->clean_gpc('g', 'add_engage_identifier', TYPE_INT);

However this code is causing a 301 redirect when accessing the home page (content.php).

When accessing the URL http://<domain-name>/ it is redirecting to http://<domain-name>/?engage_callback=0&add_engage_identifier=0

Would anyone know how to fix this?Regards

I just added that plugin to my site and I am not getting that result at all. I would guess it is another plugin you have, or other code you have added, that is actually causing this to happen.

The mod does not work as is. And developer has stopped supporting. So I have customised it to work for my site.

I tested & figured out that whatever I add in the global_bootstrap_init_start get appended in the home page URL.
For e.g:

PHP Code:

$engage_callback = $vbulletin->input->clean_gpc('g', 'engage_callback', TYPE_INT);
$add_engage_identifier = $vbulletin->input->clean_gpc('g', 'add_engage_identifier', TYPE_INT); 


Leads to URL being /?engage_callback&add_engage_identified=0

If I change it to

PHP Code:

$engage_callback = $vbulletin->input->clean_gpc('g', 'testing', TYPE_INT); 


The URL becomes /?testing=0
That is if I change the get variable to something that I'm not using in the rest of the code.

I have checked if the php variable $engage_callback has any effect. But it does not. I can change the php variable to whatever I want and there is no change in the the behaviours.

What I see in the Page Source is that the javascript code embedded in it is

var RELPATH = "?add_engage_identifier=0";

instead of

var RELPATH = "";

How does the

PHP Code:

$vbulletin->input->clean_gpc('g', 'add_engage_identifier', TYPE_INT) 


results in the RELPATH variable being filled?

And I tried disabling a few plugins that I have to isolate the problem and it doesn't seem to be due to any of them.

I moved the code & database to another server and this issue is NOT present. It seems that the some server configuration is to blame for this.

Do anyone know what config in an Apache server can cause this kind of behavior?

I've isolated the problem.

It is caused when Mod-rewrite friendly URL is turned on. When I change that setting to Basic / Advanced, there is no issue.

Any idea on what could be causing this with mod-rewrite friendly URL?

Perhaps the .htaccess is causing the issue? You may want to look at that.
