Issue with LTM Maintenance page on trial LTM VE on the Worksation

Did anybody had issues serving images and html pges from LTM VE trial version?

 

 

Seems to be that I already tried evrything and it still doesn't work properly.

 

 

Rule is applied but none of the images are displayed.

 

 

I already tried perl script to generate it and still no luck

 

 

On the side not I'm getting some weird signs at the top and the bottom of the HTML page

 

 

{ on the top and {} at the bottom

 

 

Thanks

    Seems to be the issue is with decoding. I see error messages in the log

     

     

    conversion error invoked from within ""b64decode [class element 0 img.pngl]" ("/" arm line 1

    Hi Drumik,

     

     

    Can you post anonymized copies of the iRule you're testing and the contents of the datagroup using 'b rule RULE_NAME list' and 'b class CLASS_NAME list'?

     

     

    Thanks, Aaron

    Sorry, I'm wondering if I'm missing something small. Can you either edit your post or reply again with the output in [ code ] [/ code ] tags (without the spaces)?

     

     

    Thanks, Aaron

    Problem solved

    I ended up embeding html as well as images within the IRule.
