HTTP profile breaking get requests for PDFs

Hi,

 

I have a normal HTTPS VIP offloading SSL. The HTTP VIP has a redirect to HTTPS.

 

When the client retrieved PDFs they were occasionally truncating and hence would show as corrupt. I checked the traffic trace between a good and bad example and couldn't really see any network issues. I removed the HTTP profile on the HTTPS VIP and now the PDFs are always fine. I've tweaked a few profile settings to no avail.

 

Any ideas why this is happening?

 

Thanks

    Mark,

     

    What headers are being returned when you have the http profile attached? any different when not attached?

     

    It may be a compression or a caching header causing an issue. You can amend the profile to only allow certain headers and/or create an iRule to disable either caching or compression (if that turns out to be the issue).

    Nathan,

     

    Thanks for the reply. I've checked the headers and there is no difference!

    What about Response Chunking - is that enabled in the profile? I might try selecting Unchunk.

     

    Also, does it affect all browsers?

    Nathan,

     

    I tried the chunking. But your last post I think is the answer, the cache-control.

     

    Thanks for your help.
