HTTP1.1 304 response chunking

Hi all,

 

Please help!

 

I currently have a problem relating to sol10581:Big-IP ASM chunks HTTP responses that should not be chunked.

 

I would love to be able to write an irule to resolve this by disabling chunking for 304 response messages.

 

There are a couple of similiar issues on this forum and i have tried referring to the example irules given but so far had no luck.

 

 

Can anyone help?

    Hi Rob,

     

     

    There is a hotfix for 9.4.8 and possibly other versions for CR85643. It would be simpler to fix the issue that way.

     

     

    If you couldn't install the hotfix for some reason, you would need to use a bit of a hack to be able to rewrite the response after ASM processes it. You'd need to remove ASM from the current VIP, create a second VIP with ASM enabled, use an iRule on the first, outer VIP which selects the second (ASM) VIP and then removes the 'Transfer-Encoding: chunked' header from 304 responses.
