URL Rewrite - additional symbols in second group "/?" - iis-7

I'm trying to evaluate URL Rewrite pattern, but for second value it's giving me to much:
My URL:
news/group/?page=2
My pattern:
group/([^\.]+)/?page=([0-9]+)
Group value:
{R:0} news/group/?page=2
{R:1} group/?
{R:2} 2
How to modify my pattern to have in {R:1} just "group" value?


Anwser was simply, as I wanted to have query_string as is.
I changed pattern to:
^group/([^\.]+)/$
And under action set:
<action ... appendQueryString="true" />
Which was just adding that ?page=2 query string to rewritten url.

IIS URL rewrite rule using conditions

I have the following URL rewrite rule configured in my web.config file:
<rule name="Test Rule" stopProcessing="true">
<match url="^$" />
<conditions>
<add input="{QUERY_STRING}" pattern="^(item=1|all|none|first).*$" />
</conditions>
<action type="Rewrite" url="/newsite/test.asp?{C:0}" />
</rule>
The following source url matches as expected.
http://domainname?item=1&param1=x%param2=y
However the rewritten url includes param1 and param2 in its query string. Shouldn't {C:0} only translate to what is matched in the regex group i.e. (item=1|all|none|first) and not anything that comes after it?

The reason why the rewrite captures everything after the ( ) is because {C:0} grabs the entire match, and not just the group. Since you only want to capture what is within the ( ) (which is capture group 1) you would use:
{C:1}
Another example might be:
^(item=1|all|none|first)/(abc).*$
So to capture only abc for example (capture group 2):
{C:2}

IIS URL Rewrite {R:N} clarification

I've not been able to understand the purpose of {R:N}. Could anyone please clarify when to use
{R:0} vs. {R:1}
usage example:
<action type="Redirect" url="http://www.{HTTP_HOST}/{R:0}" />
I've seen ScottGu using {R:1}
http://weblogs.asp.net/scottgu/archive/2010/04/20/tip-trick-fix-common-seo-problems-using-the-url-rewrite-extension.aspx
Whereas, below has {R:0}
http://weblogs.asp.net/owscott/archive/2009/11/27/iis-url-rewrite-rewriting-non-www-to-www.aspx
Had a look at the IIS link below but could not quite digest the definition below:
Back-references to condition patterns are identified by {C:N} where N is from 0 to 9; back-references to rule pattern are identified by {R:N} where N is from 0 to 9. Note that for both types of back-references, {R:0} and {C:0}, will contain the matched string

As per the documentation:
When an ECMAScript pattern syntax is used, a back-reference can be
created by putting parenthesis around the part of the pattern that
must capture the back-reference.
So taking the example that follows in the documentation:
^(www\.)(.*)$
And using the input string www.foo.com in the conditions, you will have:
{C:0} - www.foo.com
{C:1} - www.
{C:2} - foo.com
To make it simple:
{R:x} is used as back reference from the rule pattern (<match url="...">).
{C:x} is used as back reference from the condition pattern (<conditions><add input="{HTTP_HOST}" pattern="..."></conditions>)
The 0 reference contains the whole input string
The 1 reference will contain the first part of the string matching the pattern in the first parenthesis (), the 2 reference the second one, etc...up to the reference number 9
Note:
When "Wildcard" pattern syntax is used, the back-references are always
created when an asterisk symbol (*) is used in the pattern. No
back-references are created when "?" is used in the pattern.

IIS URL Re-write module with foreign text

We use IIS URL Re-write module, like this
<rule name="RewriteSearch" stopProcessing="true">
<match url="^Search/([_0-9a-z+-]+)" />
<action type="Rewrite" url="CommonPages/Search.aspx?term={R:1}" />
</rule>
http://www.tickettail.com/Search/NormalText123
Works fine
But...
http://www.tickettail.com/Search/ราคัดมาใ
(This is Thai)
Will not. How can I modify the match to allow foreign text?
Thanks

The regular expression to which you are matching only accepts the characters _, 0 to 9, a to z, + and -. In order to accept all characters you have to modify the regular expression to e.g. (.+) (this accepts any character and requires at least one character.
Second, in order for any character to be properly passed to the search page you have to URL encode the term by using the built in {UrlEncode:{}} function. Also make sure you page can handle and output UTF-8.
The following rules works:
<rule name="RewriteSearch" stopProcessing="true">
<match url="^Search/(.+)" />
<action type="Rewrite" url="CommonPages/Search.aspx?term={UrlEncode:{R:1}}" />
</rule>

URL Rewrite problem ,Regex expression

In my appication i used to URL Rewrite using Intelligencia.
My URL Pattern is
<rewrite url="~/([A-Za-z0-9-_ ]+)$" to="~/xxxxxx.aspx?id=$1"/>
Now i want if the URL doesn't contain iphonestatelist,iphonepropertytype then only it should redirect.
I have used this below code but it does not working.
<rewrite url="~/(^((?!\b(iphonestatelist|iphonepropertytype)\b).)*[A-Za-z0-9-_ ]+)$" to="~/xxxxxx.aspx?id=$1"/>
Eg:
The below URL dont want to Rewrite
www.xxxx.com/abc/sef/iphonestatelist
The right URL to Rewrite
www.xxxx.com/FX1234

Try
<rewrite
url="^(?!.*?\b(?:iphonestatelist|iphonepropertytype)\b)~/([A-Za-z0-9-_ ]+)$"
to="~/xxxxxx.aspx?id=$1"
/>
Generally: To check if a string contains (or does not contain) a certain sub-string, use a look-ahead (or negative look-ahead, respectively) like this:
^(?=.*?pattern-reqired)pattern-you-look-for
^(?!.*?pattern-disallowed)pattern-you-look-for
These patterns can also be chained
^(?!.*?not-this)(?!.*?not-that)pattern-you-look-for

Try
<rewrite
url="^(?!.*?\b(?:iphonestatelist|iphonepropertytype)\b)~/([A-Za-z0-9-_ ]+)$"
to="~/xxxxxx.aspx?id=$1"
/>
Generally: To check if a string contains (or does not contain) a certain sub-string, use a look-ahead (or negative look-ahead, respectively) like this:
`^(?=.*?pattern-reqired)pattern-you-look-for
^(?!.*?pattern-disallowed)pattern-you-look-for
These patterns can also be chained
^(?!.?not-this)(?!.?not-that)pattern-you-look-for`

How to use a rewrite map to replace a single querystring value with IIS 7 URL Rewrite

We have incoming URL's with querystring's like this:
?query=word&param=value
where we would like to use a rewrite map to build a table of substitution values for "word".
For example:
word = newword
such that the new querystring would be:
?query=newword&param=value
"word" may be any urlencoded value, including %'s
I'm having trouble with the regex match and substitution - I seem to get it to match, but then the substituted value doesn't get passed through.
My current rule looks like:
Match URL: Matches the Pattern: .*
Conditions: match all:
Condition 1: {QUERY_STRING} matches "query=(.+)\&+?(.+)$"
Condition 2: {rewritemap:{C:1}} matches the pattern (.+)
track capture across groups.
Action: rewrite:
rewrite url: ?query={C:1}&param=value
(I've hard coded the &param=value because it isn't changing... having that just pass through from the input would be ideal, I was just being lazy)
So write now using failed request tracking I can see it match, and seemingly replace with the mapped value, but then the url that is output still has the original value.
