URI in pools

I am running version: 4.5.13

 

 

I'm able to get the URI just fine, but when load balancing to my pool the uri (/folder) does not pass to the pool.

 

 

For Example:

 

 

url: www.testhost.com/folder --> Virtual Server(192.1.2.2) --> Test_Pool

 

 

 

Test_Pool -> Members

 

192.1.2.3/folder

 

192.1.2.4/folder

 

 

Any help would be greatly appreciated.

    Do you have a standard HTTP VIP defined which points to a pool of web servers? Or is it HTTPS?

     

     

    What happens when a client makes a request for /folder? If you use a browser plugin like HttpFox for Firefox or Fiddler for IE, do you get any response from the VIP? What does the browser display when a request fails?

    It is a standard HTTP Virtual IP not HTTPS.

     

     

    When the client makes a request I get "Problem loading page error". Using HttpFox I don't see a response from the VIP, the first thing I get back is a 300 post (Aborted) text/plain (NS_Binding_ABORTED). Using FireFox the browser displays "The connection was reset"

     

     

    Thanks in advance for any help or guidance.

    Hi Hector,

     

     

    Can you check to see if the request gets to the pool member and if so, what response BIG-IP gets from the server? You can use tcpdump to do this:

     

     

    tcpdump -ni VLAN_EXT -Xs0 host CLIENT_IP

     

     

    tcpdump -ni VLAN_INT -Xs0 host POOL_IP_1 or host POOL_IP_2

     

     

    Thanks,

    Browser displays =>

     

     

    The connection was reset

     

     

     

    The connection to the server was reset while the page was loading.

     

     

    * The site could be temporarily unavailable or too busy. Try again in a few

     

    moments.

     

     

    * If you are unable to load any pages, check your computer's network

     

    connection.

     

     

    * If your computer or network is protected by a firewall or proxy, make sure

     

    that Firefox is permitted to access the Web

    When I run the windump since this is going to a BEA webserver on Windows 2003 I get this:

     

     

    E:\WinDump>windump -i 2 tcp port 80

     

    windump: listening on \Device\NPF_{F1CD4694-2262-4405-8407-E5A43CD0982D}

    It will be most useful to get tcpdumps from both VLANs on the BIG-IP. If you need help capturing or analyzing the tcpdumps, you can open a case with F5 Support.

     

     

    For quick analysis of the traces, you can use the -X flag to write out the hex to ascii.
