[Solved] HttpHandler OutOfMemoryException

Hello Nabil Shuhaiber,

You may have discovered a bug indeed. Could you please paste here the declaration of your ScriptRegistrar? Also are you using any other components?

I have the same problem. Here is my script registrar:

 

 

Html.Telerik().ScriptRegistrar().DefaultGroup(group => group.Disabled(

true))

 

.Scripts(scripts =>

scripts.AddGroup(

"CommonScript", group =>

 

group.Add(Url.ScriptsServerPath(

"jquery/jquery-1.3.2.min.js"))

 

.Add(Url.ScriptsServerPath(

"jquery/jquery-ui-1.7.2.custom.min.js"))

 

.Add(Url.ScriptsServerPath(

"SL3/Silverlight.min.js"))

 

.Add(Url.ScriptsServerPath(

"ajax/MicrosoftAjax.min.js"))

 

.Add(Url.ScriptsServerPath(

"ajax/MicrosoftMvcAjax.min.js"))

 

.Combined(

true)

 

.CacheDurationInDays(365)

.Compress(

true)

 

 

)

)

.Render();

UrlScrptsServerPath only maps to our local scripts path.

Below you will find the rendered output in the html.

Any news on this one?

Replaying to myself here...

I think the problem is related to WebAssetRegistry::MinimumLengthToCompress .
in the compress method we have:
(target.Length > MinimumLengthToCompress): ..compress.. ? ...encode...
and in the decompress method:
(target.Length > MinimumLengthToCompress): ..decompress.. ? ...decode...

but the compress opration adds 4 bytes ( the length ) at the beginning of the stream. Either remove the minimum length check or handle the decompression differently.

Hi eti,

I think you are absolutely correct. Please use the following code in WebAssetRegistry, for the time being:

private static string Compress(string target)
{
    return target.Compress();
 }

private static string Decompress(string target)
{
    return target.Decompress();
}

Kind regards,
