Post cache substitution is not compatible with modules in the IIS integrated pipeline that modify the response buffers.
Today I upgraded my Sitefinity project to version 5.0.2860.0 Unfortunately this didn't work as expected. When I login everything seems to work as expected, but as soon I logout I get the exception underneath. I get this exception on every page except the login page. As soon as I login everything works as expected again. What have I done wrong in the upgrade?
Post cache substitution is not compatible with modules in the IIS integrated pipeline that modify the response buffers. Either a native module in the pipeline has modified an HTTP_DATA_CHUNK structure associated with a managed post cache substitution callback, or a managed filter has modified the response.
Hey El Barto,
This happens because of a default setting in the web.config in v5.0 (which will be removed in the next versions)
<
urlCompression
doDynamicCompression
=
"true"
doStaticCompression
=
"true"
dynamicCompressionBeforeCache
=
"set this to false instead of true"
/>
That solved it. Thanks Jochem
Thanks for this...got me running on arvixe after considerable consternation.
Hi,
This post is quite old, but I am having same problem with newer version of Sitefinity.
I am having similar problem where it shows this error when I logout from my website. I have another copy of website which has same web.config and I don't see this error. I checked config for dynamicCompressionBeforeCache and it is set to false for both websites (one where I have problem and one where I have not). I compared both web.config files and it does not have any difference.
I am running sitefinity 6.3.
Any help is greatly appreciated.
Thanks
Atit
