    Hi,

    I have radscriptmanager + radcompression combining and zipping up resources tremendously well on my dev environment.

    Yet despite painstakingly checking web.config / code, only the combine (not compression) works on my test server. 

    Obviously something is amiss, but do you have any ideas (IIS 7 settings?) what could be stopping this as sure code is synced and struggling to see where to look.

    Thanks
    Matt

    Hello Matthew Waring,

    There was a problem we recently fixed causing compression to be disabled at random. I suggest you upgrade to the current official release to see if it helps.

    Hi Albert!

    Tried Q3 2009, looked like it worked for 1st post! then on subsequent did not work?????

    Even worse, I have just come out of a 4 hr tailspin trying to find a new bug whereby a textbox/button click event was no longer firing!!!!!!!!

    Guess what? turning off radcompession solved this error!!!

    Have you any idea why this is happening & whether I can do the same thing with IIS7 built in compression as I no londer trust this component :(

    Regards
    Matt

    Hello Matthew,

    I am sorry to hear that you are having difficult time working with our RadCompression module. We are doing our best to address any reported issues that are confirmed by our Support Staff/QA engineers. However, there is always a possibility that an issue or a bug can slip through our test engine and get into production code.

    That is why I suggest you isolate a working case (using v2009.3.1103 of the suite) which illustrates the abnormality and send it enclosed to a standard support ticket. We will examine your code/debug the sample locally and will get back to you with our findings.

    The IIS7 built-in compression can be an alternative to RadCompression.

    Kind regards,
    Sebastian

    Hi,

    I will try at some point to isolate this, but as It seems almost random, not sure how to do so.

    In the meantime, if a fix is placed in an intermeditate build I can try can you please post to this thread so I can pick up on it.

    I am just dissappointed as Rcomp would have really finalised my remaining issues for our production server :(

    Thanks

    Hello Matthew,

    Unfortunately we are not able to confirm your observation as an issue since we do not have a test case which illustrates it. We tried to recreate it locally but to no avail. If you can isolate the problem, feel free to submit it to us and we will do everything possible to provide straight-to-the-point explanation/solution.

    Kind regards,

    Hi Sebastian,

    Yeh appreciate the need for repeat test case, but could you help me out with some guidelines of how I can troubleshoot this to narrow down causes.  I really want this to work as it will reduce my payload massively.

    1.  Need to find out why its stopping postback on certain pages, I assume it could be my jquery conflicting somehow? could this be the case?

    NEW: Just noticed this IMPORTANT INFO.

    http://localhost/pi40/default.aspx - works fine on postback fro click/enter ETC..
    http://localhost/pi40/ - does not work as above.

    Does this help?

    Also, I do employ some url rewriting for seo, but obviously have no clue as to how this could affect radcompresson?? any ideas.
    I use this scott gu? code for helping with css paths and the like + IISAPI REWRITE by helicon, its worked for years.

        End Sub 
     
    End Class

    2.  Then find out why it works on dev but not production/test server?

    i.e. How can I step through the code debug js/.net to help isolate the issue.

    I will try to strip down my code to the bare minimum and create a test solution, but there is a lot of working parts :(

    Thanks
    Matt

    Hello Matthew,

    Unfortunately from the provided details I am still not able to trace the core of the abnormality or provide suggestions what is causing it/how to fix it.

    Does disabling the url rewriter module or replacing RadScriptManager with regular MS ScriptManager fixes the erroneous behavior? You may also compare the behavior between ajax requests and plain postbacks disabling the ajax in your app and setting enablePostbackCompression = true for RadCompression as explained here.

    Also using the regular .NET code debugging techniques to follow the execution of your code and pinpoint the place when the issue occurs is something you can consider. Fiddler is a web debugging tool that can help you monitor the traffic between the client and your production server.

    Best regards,

    Hi Sebastian,

    Better news, It 'looks like' it is definetly the formrewriter.vb conflicting here with radcompression (and only this root url, i.e. /pi40/ not /pi40/default.aspx)! no idea why.  Commenting out the xml in the form.browser xml file makes it post back ok no problem.

    I got it from this article - http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

    We use ISAPIRewrite and IIS7.

    fyi: RAD vs MSScriptManager makes no difference.

    Could you please install this into your environment and see how radcompression is working with it? hope we can get to the bottom of it.

     

    Many Thanks
    Matt

    Hello Matthew,

    Does making an internal redirect call somehow from /pi40/ to /pi40/default.aspx addresses the abnormality? If this does not help, please let me know and I will continue with the investigation of the ISAPIRewrite module and will get back to you with my findings.

    Hi to all,

    I found a solution with the problem above.

    Precondition:
    - Developing with ASP.NET 4.0
    - Using RadCompression Module
    - Call the default page (Ex. www.contoso.com , not www.contoso.com/default.aspx) without specify page.

    In the ASP.NET 4.0 one important change is that if you call the default page without specify page it set the attribute ACTION for the tag FORM to be empty (Ex. <form action="" ... />); instead if you specify page like default.aspx the engine set attribute with the relative path of page specified (Ex. <form action="default.aspx" ... />).

    What happen is an incapacity for the modules to access to page properties: viewstate,form variables,etc.  (for more detail read this http://jai-on-asp.blogspot.com/2010/06/changes-and-differences-between-aspnet.html at paragraph "Event Handlers Might Not Be Not Raised in a Default Document in IIS 7 or IIS 7.5 Integrated Mode"

    So, the solution for me is to set Page.Form.Action = "Default.aspx" in page init event only for the default page.

    Have a nice xmas!

    Just spent over 2 hours trying to resolve this same problem of events not firing until finally found this post on another site:

    http://stackoverflow.com/questions/3978911/asp-net-webpage-defaultdocument-button-click-not-firing

    Then I found this page/fix (Thank you!) however have disabled RadCompression completely instead.

    To Telerik: If this problem was highlighted somewhere, I missed it. The Telerik Configuration box didn't show any alert/FYI about this critical problem using RadCompression which would've prevented all these lost hours by your customers!

    Hi Scush,

    Indeed, you are right that this issue is not documented, we will add it shortly.
    However, you should know that the problem is caused by this breaking change in .Net 4.0. You can workaround it by setting precondition="managedHandler" for the RadCompression module. Note that you may also need to remove the runAllManagedModulesForAllRequests setting from your web.config if you have it (or set it to false).

    I hope this helps.

    Kind regards,
    Iana

    Iana,

    Does this affect the performance of the RadCompression module by setting: precondition="managedHandler" from integratedMode?

    Otherwise, I could just add this as suggested below:
         Page.Form.Action = "Default.aspx"

    Thanks in advanced.

    Hi Bryan,

    Generally there is no difference between the two approaches performance-wise. However the preCondition solution might be better as it is more centralized and easier to modify.
