IIS Based Application Load balancing Issue - F5
Hi Team, We are attempting to deploy an IIS Windows-based application on F5, but it is not functioning,we are receiving only the health check responses from LB to backend server, but not any actual requests from the load balancer. Could you please assist us with any necessary steps we need to follow while configuring F5 for an IIS Windows-based application? For your information, we have applied an SSL certificate on the backend server, but not on the load balancer. Could this be causing an issue? Additionally, it would be very helpful if you could share the recommended load balancing algorithm for IIS Windows. Thanks & Regards, Shivam Aggarwal
Apm seems to strip url query
Hello I having a issue with a external weblink in a application that i access over a webportal. The problem is that the link has a authentication query in it (yeah really bad i know), and when i click on the link i land on the page but the F5 seems to have striped to query part of the link. So its like this: [https://www.webshopexample.com/cgi-bin/hej/webshop_login.cgi?USERNAME=apa&PASSWORD=sheep](https://www.webshop.com/cgi-bin/hej/webshop_login.cgi?USERNAME=apa&PASSWORD=sheep) Gets [https://www.webshopexample.com/cgi-bin/hej/webshop_login.cgi](https://www.webshop.com/cgi-bin/hej/webshop_login.cgi) Any idea?
BIG-IP : iRule case-insensitive query-param matching
F5 BIG-IP Virtual Edition v11.4.1 (Build 635.0) LTM on ESXi In my iRule I wish to identify the value of a query-param that may or may not be present. I'm using this logic : set myparam 0 set myparam [URI::query [HTTP::uri] myparam] However, I'm finding that URI::query performs case-sensitive matching. For example, if my request is : http://www.mysite.com/hello?myParam=1 then the myparam variable will not be set. Howe can I perform case-insensitive matches of query-params ?How can I remove a query parameter from a URL?
I'm trying to remove a query parameter from a URL, and I'm stuck... Basically, I may have 0-n parameters appended to a querystring. They will all have a similar name, starting with "Context_", e.g. "Context_Site", "Context_Device_Type", "Context_Platform". My original plan was to remove the parameters using the following code (which I got from another question on this forum that I can no longer find.: when HTTP_REQUEST { if {[HTTP::query] contains "Context_"} { set newq "" Split query string into separate parameters foreach param [split HTTP::query] "&"] { Only add non-context query parms into newq if {!($param starts with "Context_")} { if {$newq eq ""} { append newq "?$param" } else { append newq "&$param" } } Add new query portion to path if {$newq ne ""} { HTTP::uri "[HTTP::path]$newq" } else { HTTP::uri [HTTP::path] } } } } The thing is, when I try to run this in Tcl for Windows (Tcl 8.5.8, Tk 8.5.8), I get an "invalid bareword" error for the "contains" in the second line: invalid bareword "contains" in expression "[HTTP::query] _@_contains "Context_..."; should be "$contains" or "{contains}" or "contains(...)" or ... I think the syntax is correct, so is this due to a problem with the version of Tcl I'm using? Also, on a related note (and I can ask this as a separate question if it makes sense), if I know that the Context_ parameter(s) will be the last parameter(s) in the URL, is there a better/faster way to remove them than to parse out the querystring into its individual parameters and check each one in turn? For instance, could I just search for the first instance of "&Context_"in HTTP::query and just strip out everything from that point on (also checking for HTTP:query starts with "Context_", I guess).

Configuring LDAP Auth and Query APM
Hi All/DC Experts, I am confused what I need to enter on this type of authentication. Actually I already managed to import groups into f5. The problem is I can't authenticate. Any suggestion/comments are really appreciated. Thanks. -NatQuery / Monitor last failover time
Hello, I have a pair of LTMs that were toggling active-standby-active. We've resolved the issue, but I'd like to detect this in the future. Is there any way to programmaitcally (i.e. something that I can script) check the time of the last failover event, or how many failover events have happened (i.e. cache a counter, and see if it increases)? So far the only thing I've been able to come up with is looking in /var/log/ltm, which is a pretty expensive operation given that we have a LOT of iRule logging going there. Thanks, Jason
