Hello,

I have bought 3 licences, my registration name is CHAPS spol. s r.o. I use ISAPI Rewrite version 3.1.0.44, used system is MS Server 2003 SP1. 

Problem is, taht ISAPI rewrite sometimes match rule and sometimes the same rule do not match. Problematic rule is: RewriteRule AJAXService\.asmx(.*)$ $0 [NC, L, QSA].

In the version 3.1.0.32 it seems OK. But now I download new x64 version, becasue our application migrate to x64 system.

I attached a Rewrite.log file fragment. The first row documents the error, the other lines shows success match of the rule. On the first row is also any suspect string: "rid#17899160/initial/1".

Can you help me? thanks

hi, your suggestion unfortunately do not work.

You suggest do not change requests that target to file AJAXService.asmx, but I need change them! I need to cut the prefix, so I thing that my rule RewriteRule AJAXService\.asmx(.*)$ $0 [NC, L, QSA] is OK.

For example I need the reqeuest "vlakyautobusy/spojeni/AJAXService.asmx/SearchOnGlobalList"  change to "AJAXService.asmx/SearchOnGlobalList".

ISAPI Rewrite sometimes this change perform but sometimes not.

I attach a fragment of Rewrite.log file. Here is to see that first and second request are not changed (there is only one line about this request). But the third request is chaged OK (there is 9 lines about this request).

----------------------------------

In the version 3.1.0.32 this work fine. Is there any changes list between this version and the version 3.1.0.44? May by is there any changes, that I missed.

Thanks for your help

Excuse me, but what should happen? I add a NS flag to problematic rule and nothing changed. (In your documentation is NS flag described as "Unsupported. Meaningless for IIS." Is it OK?)

Is it possible to download ISAPI Rewrite version 3.1.0.32 for 64-bit system? Because I use version 3.1.0.32 for 32-bit system and it works fine. I need quckly migrate my application to 64bit system, so I think that version 3.1.0.32 x64 can resolve my problems.

I attached log files created with the flag NS in then rule.

Here is fragment of Rewrite.log, problematic behaviour you can see at the first and second line:

thanks

Thanks for versin 3.1.0.32 x64! I migrate my application to 64bit system and with this version it works fine.

I change my RewriteRule by your pattern, but on the version 3.1.0.44 it always get the same problem. But when I uninstall version 3.1.0.44 and install 3.1.0.32 it start work OK.

I use only automatical installation of ISAPI Rewrite, I do not make any changes to the default values. I never install ISAPI Rewrite manualy.

So I think that in the version 3.1.0.44 is any bug. If you wish I can help you find it. If you get me access to download all the versions from 3.1.0.32 to 3.1.0.44 I can try install them and find which version still work and which not.

thanks

We checked the rights, all seems OK. We installed version 44 and using Filemon.exe we filtered access to file .htaccess. Here are the results:

We have only one file C:\appwww\idos\.htaccess. Directory C:\appwww\idos is app root. As you can see, ISAPI_Rewrite tries to open .htaccess many times even in virtual directories, eg. C:\appwww\idos\vlaky originates in RewriteRule. Lines 57-59 from the listing lead to HTTP500 error.

Any advice?
