What's wrong with this regular expression

[tisa Profile]

Hi ALL,

I don't understand that why my following regular expression can't work on RegExp Test. Can someone help me find the problem? Thanks a lot!

^subcategory\.aspx\?CatgId\=1\&subCatgId\=([0-9]+)
teststring: subcategory.aspx?CatgId=1&subCatgId=50011995

Thank you very much

The thing is that in ISAPI_Rewrite 3 the query string is matched separately:

RewriteCond &{QUERY_STRING} ^CatgId=1&subCatgId=(\d+)$ [NC]
RewriteRule ^subcategory\.aspx$ ...

Thanks for your reply, Anton.

I have try this
RewriteCond %{QUERY_STRING} ^CatgId=1&subCatgId=(\d+)$ [NC]
RewriteRule ^subcategory\.aspx$ /skincare/%1 [NC,L,R=301]
but it doesn't work. %1 cannot bring value to /skincare/%1

like this
subcategory.aspx?CatgId=1&subCatgId=123
=>
/skincare/ <= no value after skincare

thanks

"but it doesn't work. %1 cannot bring value to /skincare/%1"
- this is strange as the rule looks fine.

Please confirm you are using ISAPI_Rewrite v3.

Enable logging by putting the following in httpd.conf:

RewriteLogLevel 9

and provide rewrite.log records for the test request subcategory.aspx?CatgId=1&subCatgId=123
