Version-Release number of selected component (if applicable): Server version: Apache/2.2.3 Server built: Apr 4 2010 17:18:37 How reproducible: Add more than 50 VIPs in a machine running piranha, and the edit option for VIPs stops work. Steps to Reproduce: 1. In a host running piranha add more than 50 VIPs 2. Try to edit a VIP 3. See the error in the screen Actual results: Too Many arguments in the URL Expected results: The edit options for the selected VIP Additional info: Changing some lines in the virtual_main.php file works again: [root@lb1 secure]# diff virtual_main.php virtual_main.php.orig 5,6c5,6 < if (isset($_POST['selected_host'])) { < $selected_host=$_POST['selected_host']; --- > if (isset($_GET['selected_host'])) { > $selected_host=$_GET['selected_host']; 8,9c8,9 < if (isset($_POST['virtual_service'])) { < $virtual_service=$_POST['virtual_service']; --- > if (isset($_GET['virtual_service'])) { > $virtual_service=$_GET['virtual_service']; 97,98c97,98 < if (isset($_POST['virtual_service'])) { < $virtual_service = $_POST['virtual_service']; --- > if (isset($_GET['virtual_service'])) { > $virtual_service = $_GET['virtual_service']; 133c133 < <FORM METHOD="POST" ENCTYPE="application/x-www-form-urlencoded" ACTION="virtual_main.php"> --- > <FORM METHOD="GET" ENCTYPE="application/x-www-form-urlencoded" ACTION="virtual_main.php"> [root@lb1 secure]# --- Additional comment from mgrac on 2011-05-26 11:31:21 EDT --- @Carlos: Thanks for a patch, I will clone it to RHEL5 and RHEL6 where it can be fixed. RHEL4 is now in very late stage and only very important and security fixes can be included. Situation differs for newer versions where this kind of bugs should be surely fixed and yours patch provides a good solution.
Created attachment 517440 [details] Replace HTTP GET with HTTP POST in virtual server UI. This is a formal patch identical to the one posted in comment #1.
I've applied the patch and was able to add/edit/delete VIPs where I once hit the "Request-URI Too Large" error. On the same system that hit problems after 92 VIPs were defined, I applied the patch and was able to continue adding, editing, and deleting VIPs. I added 100 VIPs. # egrep ^virtual lvs.cf | wc -l 100
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Previously, the piranha-gui utility reported an HTTP 414 error (Request-URI Too Long) if too many virtual servers were defined. As a consequence, when trying to edit a virtual server, the error message "Too many arguments in the URL" appeared. With this update, the number of defined virtual servers does not affect the length of the URI. Now, error messages are no longer reported.
