Converting to web.config from ISAPI Rewrite 3

[AndyM2 Profile]

Hi

We've been running your excellent ISAPI rewrite for a few years now and our hosts have now decided to migrate to IIS7, I was wondering if you knew of the best way to convert the rules created by ISAPI re write into web.config compatible rules.

The re writes we are using use text files to get the correct I'd etc, the code is as follows

Code: Select all

RewriteRule ^scaser\.asp$ range/%2/${showcaserange:%1}.asp? [NC,R=301,L]
RewriteRule ^range/(\d+)/([^?/]+)\.asp /scaser.asp?RID=${revshowcaserange:$2}&offset=$1 [NC,L]

RewriteCond %{QUERY_STRING} RID=(.*)$ [NC]
RewriteCond ${showcaserange:%1|NOT_FOUND} !NOT_FOUND
RewriteRule scaser\.asp$ range/${showcaserange:%1}.asp? [NC,R=301,L]
RewriteRule ^range/([^?/]+)\.asp /scaser.asp?RID=${revshowcaserange:$1}

RewriteMap showproducts txt:showcaseproducts.txt
RewriteMap revshowproducts txt:revshowcaseproducts.txt

RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteCond %{QUERY_STRING} SPID=(.*)$ [NC]
RewriteCond ${showproducts:%1|NOT_FOUND} !NOT_FOUND
RewriteRule spod\.asp$ showcaseproduct/${showproducts:%1}.asp? [NC,R=301,L]
RewriteRule showcaseproduct/([^?/]+)\.asp /spod.asp?SPID=${revshowproducts:$1} [NC,L]

RewriteMap category txt:category.txt
RewriteMap revcategory txt:revcategory.txt

RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteCond %{QUERY_STRING} CatID=(\d+)&offset=(\d+)$ [NC]
RewriteCond ${category:%1|NOT_FOUND} !NOT_FOUND
RewriteRule ^products\.asp$ categories/%2/${category:%1}.asp? [NC,R=301,L]
RewriteRule ^categories/(\d+)/([^?/]+)\.asp /products.asp?CatID=${revcategory:$2}&offset=$1 [NC,L]

RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteCond %{QUERY_STRING} CatID=(.*)$ [NC]
RewriteCond ${category:%1|NOT_FOUND} !NOT_FOUND
RewriteRule products\.asp$ categories/${category:%1}.asp? [NC,R=301,L]

Hello,

It seems that you'd like to migrate to microsoft default rewriting tools. There should be a microsoft .htaccess migration feature, and your rules look easy enough for it(I'm also more proficient in ISAPI_Rewrite syntax rather than Microsoft's and couldn't help much).

As a workaround we can suggest HeliconApe. It was designed specifically for IIS7+, it's free for up to 3 web-sites per server and it has the same syntax as ISAPI_Rewrite3.

Nice one thanks ill see what they will let us do

[AndyM2 Profile]

we've managed to get the hosting company to install APE but some of the redirects are causing loops...any suggestions?

the one in particular is

RewriteMap products txt:products.txt
RewriteMap revproducts txt:revproducts.txt
RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteCond %{QUERY_STRING} PID=(.*)$ [NC]
RewriteCond ${products:%1|NOT_FOUND} !NOT_FOUND
RewriteRule product\.asp$ product/${products:%1}.asp? [NC,R=301,L]
RewriteRule product/([^?/]+)\.asp /product.asp?PID=${revproducts:$1} [L]


cheers

[HeliconAndrew]

Try to add NS-flag to all the rules like this. NS flag has slightly changed compared to ISAPI_Rewrite3

[AndyM2 Profile]

Thanks andrew that appears to have worked on evertything apart from the following

RewriteMap products txt:products.txt [NC, NS]
RewriteMap revproducts txt:revproducts.txt [NC, NS]

RewriteCond %{REQUEST_METHOD} !^POST$ [NS]
RewriteCond %{QUERY_STRING} PID=(.*)$ [NS]
RewriteCond ${products:%1|NOT_FOUND} !NOT_FOUND
RewriteRule product\.asp$ product/${products:%1}.asp? [NC,R=301,L,NS]
RewriteRule product/([^?/]+)\.asp /product.asp?PID=${revproducts:$1} [NC,L,NS]

any suggestions?

[HeliconAndrew]

Try the following modification:

RewriteCond %{REQUEST_METHOD} !^POST$ [NS]
RewriteCond %{QUERY_STRING} PID=(.*)$ [NS]
RewriteCond ${products:%1|NOT_FOUND} !NOT_FOUND
RewriteRule ^product\.asp$ product/${products:%1}.asp? [NC,R=301,L,NS]
RewriteRule ^product/([^?/]+)\.asp /product.asp?PID=${revproducts:$1} [NC,L,NS]

All i did - add the '^' to show the beginning of the pattern.

Andrew

Thanks, that still seems to be giving the same, result, any other suggestions? the url bar seems to go to index.asp if that helps?

[HeliconAndrew]

We have no other choice but to start looking at the logs. PLease, create a rewrite.log with a testing request.
