Question

i need some help to write two URL rewrite rules in IIS7, i have tried for the last 3 hours with no success.

Basically, i have the following two rules:

<rule name="Resize Images - Game Thumbnails - Static" stopProcessing="true">
    <match url="^images/c/games/(.+)x(.+)/(.+)$" />
    <conditions logicalGrouping="MatchAny">
        <add input="\mycms\games\images\thumbs\220x150\{R:3}" matchType="IsFile" negate="true" />
    </conditions>
    <action type="Rewrite" url="/mycms/games/images/thumbs/{R:1}x{R:2}/{R:3}" />
</rule>
<rule name="Resize Images - Game Thumbnails - Dynamic" stopProcessing="true">
    <match url="^images/c/games/(.+)x(.+)/(.+)$" />
    <conditions logicalGrouping="MatchAny">
        <add input="\mycms\games\images\thumbs\{R:1}x{R:2}\{R:3}" matchType="IsFile" negate="true" />
    </conditions>
    <action type="Rewrite" url="/controls/makeThumb.aspx?folder=games&amp;image={R:3}&amp;w={R:1}&amp;h={R:2}" />
</rule>

Both of the rules work if they are alone.

for example, if i put only the static rule, and the image exists,
Then it returns the image.

if i leave only the dynamic rule, and the image does not exist,
then it is created.

but why don’t the rules work together?

Answer 1

Well i found the problem,
basicly both of these rules work:

        <rule name="Resize Images - Game Thumbnails - Static" stopProcessing="true">
            <match url="^images/c/games/(.+)x(.+)/(.+)$" />
            <conditions logicalGrouping="MatchAny">
                <add input="{APPL_PHYSICAL_PATH}mycms\games\images\thumbs\{R:1}x{R:2}\{R:3}" matchType="IsFile" />
            </conditions>
            <action type="Rewrite" url="/mycms/games/images/thumbs/{R:1}x{R:2}/{R:3}" />
        </rule>
        <rule name="Resize Images - Game Thumbnails - Dynamic" stopProcessing="true">
            <match url="^images/c/games/(.+)x(.+)/(.+)$" />
            <conditions logicalGrouping="MatchAny">
                <add input="\mycms\games\images\thumbs\{R:1}x{R:2}\{R:3}" matchType="IsFile" negate="true" />
            </conditions>
            <action type="Rewrite" url="/controls/makeThumb.aspx?folder=games&amp;image={R:3}&amp;w={R:1}&amp;h={R:2}" />
        </rule>

BUT!!!! and this is a big but,
if you delete the image ( for testing purposes or whatever )
the rule is somehow cached, and for some bizzare reason, the dynamic rule will not execute.
the only way to force it to execute, is to recycle the application pool.
