Dear Support Team, dear Community,
after trying the SlickUpload local in my MVC 3 Application, I now decided to run some tests on my Win2k8 R2 Server, but sadly I do not get it running.
First of all, after submitting the file and upload nearly has finished, I get the JS-Error message: "DEBUG MESSAGE: Could not contact SlickUpload request progress handler at "/SlickUpload.axd".". Of course the validation then only posts: "Error Summary: Other".
I double checked my Version (6.1.3, 2nd of November) and the SlickUploadDiagnostics.aspx, which says that everything is fine.
I'm running the Application on IIS 7.5, integrated mode, .Net 4.
Here's a part of my Web.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration> <configSections> <section name="slickUpload" type="Krystalware.SlickUpload.Configuration.SlickUploadSection, Krystalware.SlickUpload" requirePermission="false" /> </configSections>
[...]
<system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <add name="SlickUploadModule" type="Krystalware.SlickUpload.Web.SlickUploadModule, Krystalware.SlickUpload" preCondition="integratedMode" /> </modules> </system.webServer> <location path="SlickUpload.axd"> <slickUpload> <uploadParser handleRequests="true"/> </slickUpload> <system.web> <httpRuntime maxRequestLength="2024000" executionTimeout="300"/> </system.web>
<system.webServer> <security> <requestFiltering> <requestLimits maxAllowedContentLength="2072576000"/> </requestFiltering> </security> </system.webServer> </location>
[...]
<slickUpload> <uploadProfiles> <add name="default"> <uploadStreamProvider type="File" location="~/upl/originals" existingAction="Rename" /> </add> </uploadProfiles> </slickUpload> </configuration>
I really appreciate any help!
Best Regards, Phil

From what I see, that looks correct. Can you send your entire web.config to me at chrish@krystalware.com so I can take a look and see if there may be anything else interfering with the upload?
A few questions:
- Do you have any other IIS modules (ISAPI, HttpModule, etc.) installed?
- Do you have any network devices that may be filtering large POST's (firewalls, etc.)?
- Do you get the message randomly, or every time?
- Does doing a certain thing seem to bring up the message?
- Which browsers are you seeing the issue in?
- What version of IIS are you running on the server?
Also, try updating to our latest 6.1.4 build: http://krystalware.com/files/SlickUpload-6.1.4.zip. It doesn't have a fix for this particular issue, but it solves a couple of other issues and I want to make sure you're up to date before we start trying to reproduce the issue.

We discovered an issue with that 6.1.4 build. A new, fixed build is now up here: http://krystalware.com/files/SlickUpload-6.1.4-Fixed.zip

First of all, thank you very much for this quick reply!
I tested the 6.1.4-fixed with the same result as before. The only Modules I can think of are UrlRewrite and the Enyim-Membase-Client. Also we do not have any filtering of large POSTs, even the smallest ones throw this error, every time we try. I do get this error every time, in the latest Firefox as well as with any WebKit-Browser. As I mentioned before, we are running the IIS 7.5.
I will mail you the complete Web.config in a minute.
Thank you so far!
Best Regards, Phil

The web.config looks good -- I don't see any issues.
Is there any way you can disable those modules just to see if that helps, or would that break your application?
Do you get the same error in IE?

If I disable the UrlRewrite I can't access the MVC-Application anymore - which makes sense, as it's all based on UrlRewriting.
For Eniym I need to make some changes in my Project, so I need some more time for testing on that.
And yes, in IE I get the same error...
Any other Ideas?

Is there any way you can send me the url and some credentials I can use to get into the application and attempt to reproduce from my end?

Okay, somehow the error is gone by now.
I just recomiled all over again, erased the whole folder, resetted the website completely, uploaded everything again, and now it works somehow!
Thank you very much for all your advices!
