Progress page fails on large downloads

Good morning everybody

We used to discover many times that the progress page fails on large downloads. Digging in that forum for a solution was without success so far so usually we configure in such a situation just an exception for the specific url which causes it to fallback to data trickling.  This is our rules which are pretty common or let me say, just default:

Today a user wants do download that file: http://www.myigel.biz/public/IGEL_UNIVERSAL_DESKTOP_FIRMWARE/LX/V5/lx_5.05.100_public.zip, size is about 618.9 MB. The download link is provided on the url  http://www.myigel.biz/index.php?dir=IGEL_UNIVERSAL_DESKTOP_FIRMWARE/LX/V5/.

The progress page does not appear and after a while I get that message:

progress_page2.JPG

So the download may have been down however I'm missing somehow the link to that file. As I'm preparing for the upgrade to the latest version of 7.5.0.3 I had the chance to work on that issue on two versions, that is 7.3.0.2 and 7.5.0.3. No differences at all, same behaviour in both versions. This is what my debug log says:

DEBUG RULESET:  [12/Jan/2015:17:30:19 +0100] ****** 4 46.30.212.83  http://www.myigel.biz/public/IGEL_UNIVERSAL_DESKTOP_FIRMWARE/LX/V5/lx_5.05.100_public.zip?forcedownl...   Add debug logging Enable Debugging and Logging, Enable Rule Tracing, Add debug logging, Global Blacklist, Global Whitelist, Authenticate and Authorize, Get Credentials from downstream Proxy, X-Authenticated-User, X-Authenticated-Groups, X-Forwarded-For, Authorize, Define properties based on group membership, Check if user belongs to ksgr, SSL Scanner, Common Rules, Remove Header: Via, Handle Special Sites, Web Cache, Read From Cache, Enable Web Cache, Progress Indication, Enable Progress Page, Enable Opener, Enable Composite Opener, URL Filtering, URL Filtering Whitelist, URL Filtering ksgr_internet_informatik, Set Group Processed, Media Type Filtering, Gateway Anti-Malware, Remove Partial Content for HTTP(s) Requests, Enable Debugging and Logging, Enable Rule Tracing bg_navbar.jpg logo.png ###

So according that logs the progress page rule is triggered, however as mentioned the progress page is not displayed.

Configuration is two physical nodes (WG4500) in central management cluster mode (ProxyHA).

Many thanks for your help.

Re: Progress page fails on large downloads

I've tested your request on our WS5500-C running Version 7.4. We receive the progresspage without any problems.

Did you try to bypass the AV engine for this link?

Just tested, no changes as expected ... because the first state on the progress page would inform about the download status, and not even this is displayed. Does your configuration in about match my configuration? (regarding the progress page)

I am also offering you to download it in disabled form of progress indicator rule to see that is it your web gateway's problem or something is wrong with your network.

Re: Progress page fails on large downloads

After further investigation on that issue it seems that we have a general problem downloading files greater than ~100M. Downloading a 100M File from http://www.thinkbroadband.com/download.html works fine, progress page is displayed and so on as you would expect. Downloading the 200M file from the same site stucks, no progress page is displayed. The logs in access.log does not show any hint on the issue. Once I disable the progress page rule the download falls back to the data trickling rule which works.

Can anybody confirm for that experiences?
