missing HTTP_RESPONSE_DATA when Web Accelerator is enabled

  Hi,     We've written a custom iRule based on the anti-phishing iRule posted on DevCentral (very helpful, BTW) to inject some custom HTML content and it is working well. However, we ran i...

Hi Colin,

 

 

Here is a update in case you were' tracking this:

 

 

So the mystery has been solved, but the issue turns out to be completely different than expected. After much experimentation and luck, I was able to get the CreditCardScrubber iRule working against the test chunking site by change the HTTP::collect parameter from the default 4294967295 (4+ gigs) to an apparently more manageable 1000000000 (1 gig).

 

 

I don't know for sure why, but I suspect that some memory allocation is failing with the larger collect parameter. I went to 3 gig and was able to see intermittent failures to get HTTP_RESPONSE_DATA. I found 2 gig to be very consisten in being successful, but set it at 1 gig to be safe. Unlikely any HTML page will be 1 gig in size in any case.

 

 

I will also post a separate message that better describes the core issue.

 

 

Thanks again for your help!
