Problems downloading files with CACHE-CONTROL header

Hi

I have hit this problem recently too. In my case relating to a problem with Internet Explorer not being able to download files from a website over https. Problem doesn't exist in firefox.

We have got round the problem by forcing the removal of all cache control headers on the virtual servers controlling the affected website. We were concerned that this might mean that data driven downloaded files would cache when we didn't want them too, so we just ensured every download file was generated with a different name on the fly making the caching irrelevant. Low usage 'extranet' type website so cache performance wasn't key, where the functionality was.

The irule was found elsewhere on DevCentral

 
when HTTP_RESPONSE { 
     Remove all Cache-Control related headers 
     Solves issue in IE when downloading over https fails
    HTTP::header remove Cache-Control 
    HTTP::header remove Expires
    HTTP::header remove Pragma  
 }
