PhpBB problem

by **OutlawTorn** » Wed Apr 28, 2004 4:46 am

Alright since this board is running a modified version of phpbb i will ask my question.

Ok when someone goes to login, they enter thier login info and then press login. Now the login page will hang untill you either get a 404 error or "recieved no data from host". But when the user would press refresh or click back, poof thier logged it. Now why is it that the login hangs and goes to a 404 error like the login failed or something but yet when u refresh to the main index or click back thier logged in.

This person is using Internet Explorer aren't they? Here is what is most likely happening: The browser (probably IE) is incorrectly detecting a 404 (which happens often with IE). The header from the server is being sent, IE is parsing the Set-Cookie header and "setting" the cookie. As just mentioned, even though the cookie is set, IE still "senses" a 404 or something for some unknown reason. Thus, even though a proper header was sent from the server and the cookie was set, you still get a 404. When you hit refresh, the cookie has been set, so IE sends it in the request. The server receives the request with the cookie that IE set before. This cookie contains the PHP Session ID, and the server thinks the user has logged in, thus you are redirected to a page and logged in.

An understanding of HTTP and cookies definitely helps to understand the process.

Oh yeah, I could be wrong...

Its not browser, its either the code or the domain info, cuz everyone is having the problem when they visit the forum

ahh so it may be the cookies that is sent from the server to the host user. Ill have to look at the code in phpbb and see how cookies are sent/handled

Oh and it happens in IE or Mozilla

Okay, I think I may have got it, I had to do a whole rewrite in /includes/functions.php; the entire code section from "function redirect($url)" to the final "}" with the code below:

Code: Select all: function redirect($url) { global $db, $board_config; if (!empty($db)) { $db->sql_close(); } $server_protocol = ($board_config['cookie_secure']) ? 'https://' : 'http://'; $server_name = preg_replace('#^\/?(.*?)\/?$#', '\1', trim($board_config['server_name'])); $server_port = ($board_config['server_port'] <> 80) ? ':' . trim($board_config['server_port']) : ''; $script_name = preg_replace('#^\/?(.*?)\/?$#', '\1', trim($board_config['script_path'])); $script_name = ($script_name == '') ? $script_name : '/' . $script_name; //$url = preg_replace('#^\/?(.*?)\/?$#', '/\1', trim($url)); // Redirect via an HTML form for PITA webservers if (@preg_match('/Microsoft|WebSTAR|Xitami/', getenv('SERVER_SOFTWARE'))) { header('Refresh: 0; URL=' . $server_protocol . $server_name . $server_port . $script_name . $url); echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><meta http-equiv="refresh" content="0; url=' . $server_protocol . $server_name . $server_port . $script_name . $url . '"><title>Redirect</title></head><body><div align="center">If your browser does not support meta redirection please click <a href="' . $server_protocol . $server_name . $server_port . $script_name . $url .
