vbSEO - Query strings and under the hood

Hello all,

I am currently developing a vBulletin modification that does some work with the query strings passed to scripts. However I am coming across a problem which I believe to be related to how vbSeo handles/appends to query strings, so I need some details of what vbSeo is doing under the hood in relation to query strings.

As an example if navigate to my "off topic" forum:

http://www.mysite.com/off-topic/

and run the following basic script code in the init_startup hook

Code:

print "<pre>";
print_r($_GET);
print "</pre>";
print "Server Vars: $HTTP_SERVER_VARS['QUERY_STRING']";

The output I get is:

Array
(
[vbseourl] => off-topic/
[f] => 10
[forumid] => 10
)

Server Vars: f=10

So it looks like vbseo is adding the query string values seen in $_GET and some of these make it to HTTP_SERVER_VARS. I assume it then invokes the forumdisplay.php script with these.

I know I haven't really asked a question here, this is because I am not sure what question I need to ask, so I suppose the question is: How does vbSeo work with query strings?

Hello,

yes, this is basically correct - vBSEO "preprocesses" rewritten URLs, extracts the details from them and then is "reconstructing" the original URL as if it was not rewritten, including restoring $_GET/$_REQUEST parameters and QUERY_STRING.
