First LTM/Web Accelerator Implementation

Hi everyone, I'm going to configure for the first time LTM with WA, it's a stand alone configuration, this is basically what I'm going to do, I just need to know if it's ok:

 

 

1. create internal vlan

 

2. create self ip for internal vlan

 

3. Add node (just one in the beggining because the web site is in production)

 

4. create pool

 

5. create virtual server:

 

-http profile

 

6. configure SNAT Automap and enable on virtual server

 

7. create http class profile and asociate it to the virtual server

 

8. create application profile and apply a general policy

 

 

This is what I have so far, but I'm still confused on the host map part of the configuration I am trying to improve the loading time of a website.

 

 

Thank you very much :)

    Hi,just reusing your post:

     

    To my understanding from here I think you need to do this to have enabled web acceleration module (WAM) for your traffic:

     

    1. create standard LTM config - VIP, pool, assign http profile, snat if need
    2. create custom web acceleration profile (basically http cache profile)
    3. create new WAM application and assign it to web acceleration profile created in previous step
    4. assign web acceleration profile to the VIP

    Can anybody agree this is the correct way to configure WAM for http services? Why then in HTTP classes is switch named "WebAccelerator" with options accelerated/bypass?

     

    Do I need to use this HTTP class, or is it just another way how to use WAM for http traffic? Thanks, Zdenek

    Is there nobody who knows why there is WAM option in HTTP class eventhough it seems it is not needed?

    HTTP Class profiles ceased to exist in 11.4, they've been replaced by HTTP Policies. In versions using HTTP Class profiles consider them to be the link between LTM and WAM.

     

    Client -> VS -> TCP Profile -> HTTP Profile -> HTTP Class -> WAM Host Map -> WAM Policy -> HTTP Class -> Pool -> Server

     

    When the HTTP Class profile match rules match the traffic and the Web Acceleration tickbox is on the traffic goes from LTM -> WAM. In WAM the Host Map then directs the traffic to the correct policy. It matches the Host: header and picks the appropriate policy to use for acceleration.
