iRule causing requests to be duplicated (sometimes)
We are using an iRule to manage access to a SPA, which requires REWRITE to be disabled. Without this rule the SPA application does not work. However, when the rule is enabled we are seeing duplication of requests within our other (non SPA) applications. We notice this especially with file uploads and SQL insert requests. If we remove the iRule the non SPA applications work correctly, but the SPA application does not. Here is the iRule. ----- when REWRITE_REQUEST { if {[HTTP::uri] starts_with "/apps/appname/uid/sso"} { REWRITE::disable } } when REWRITE_REQUEST_DONE { if {[HTTP::uri] starts_with "/uid"} { REWRITE::disable } if {[HTTP::uri] starts_with "/apps/appname/uid/sso"} { REWRITE::disable } REWRITE::post_process 1 }

"Configuration problem" when setting up a trial LTM VM
I have downloaded the 90 day trial version of LTM VE and am having trouble configuring it. I have installed it on an ESXi server and run 'config' to set up a static IP address for the management interface. However this is not persistent - if I reboot the VM the IP address gets forgotten and I have to re-enter it. Next I managed to log into the UI and install the trial license. However the UI then displays this message when logging in: This BIG-IP system has encountered a configuration problem that may prevent the Configuration utility from functioning properly. To prevent adverse effects on the system, F5 Networks recommends that you restrict your use of the Configuration utility to critical tasks only until the problem is resolved. Beware that attempting to modify your configuration in this state with the Configuration utility may cause your configuration to be overwritten. and when I have logged in I get this across the top of the page: The configuration has not yet loaded. If this message persists, it may indicate a configuration problem. and most UI options just show the message "An error has occurred while trying to process your request." So what have I done wrong, and how do I fix it?

"No handler" errors
Hi, on a production LTM, we are currently experiencing intermittent connectivity problems to some of the VIPs. With the "tmsh show /sys tmm-traffic", I see a relativelly large number of "No handler" errors. Other error counters in the same output are zero. Does anybody have an idea what do these errors indicate?
