Issues with URL rewriting?

Reply Quote

Are there any know issues with using the UploadAttachments control with a url rewrite module (like the IIS7 rewrite module)? I have a page the works fine when the url rewriting is turned off, but I get a strange 404 error when URL rewriting is turned on. Firebug reports a 404, but the trace logging in IIS reports a 200 status code (OK). Im trying to determine if there is an issue with my rewrite url somehow not handling the request that the control is posting. From looking at the request, it looks fine. Any known issues wth rewriting or tips for where I should look?

Here are the IIS trace logs of two requests; one that worked and one that didnt. They are very similar, and I cant see anything that would cause an issue. Thoughts?

Hi,

Can you post your url configuration?

you need handle the conditions of the querystring which be added by uploader.

Terry

Here is the rule. The default is that it passes on request parameters.

        <rule name="Report_Create_Area_Rewrite" stopProcessing="true">
          <match url="^report/create/area/("d+)/?"/>
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/>
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/>
          </conditions>
          <action type="Rewrite" url="components/report/create.aspx?areaID={R:1}"/>
        </rule>

To make sure the rule was working I tested the URL bellow and that page loaded properly (however uploading was still broken).

http://localhost/report/create/area/820/?useless=true

From reading the other posts, my issue seems a bit similar to this one...

Hi,

It seems that your are using IIS7 url rewrite module.

I sugguest you keep the querystring like this:

(maybe you need modify the pattern a little to make it works)

One thing Ive noticed from comparing the trace logs is that the failure case doesnt have the correct data for GENERAL_REQUEST_ENTITY. It seems to be missing the form post data somehow.

That sounds like an IIS7 bug very similar to...

I tried you suggested regex changes, they did not resolve the issue.

Thanks for trying though!

Hi,

I just found that the uploader try to access the

components/report/create?areaID=820

That's the problem.

Can you show me the HTML source code ? what is the form action ?

Terry

Hi,

I think you also need change the pattern

components/report/create

109.

PATTERN_MATCH

Pattern="^components/report/create", InputURL="components/report/create", Negate="false", Matched="true"

Terry

Hi,

I just checked all logs..

The form data is OK, the upload module can read it.

after Response.Write("OK") , there is a GENERAL_NOT_SEND_CUSTOM_ERROR

Maybe the error is that , the uploader module do not set Response.StatusCode=200 before Response.Write("OK")

I will create an application and test it in my PC and then give you a response.

Regards,

Terry

Here is a clean failure trace. In it you can see the original url is ...

report/create/area/820/

this is rewritten to...

components/report/create.aspx?areaID=820

The trace shows this match on line 116.

The final url is...

http://localhost:80/components/report/create.aspx?areaID=820&UseUploadModule=Dynamic&_Namespace=CuteWebUI&_UploadID=ctl00_ctl00_ContentPlaceHolderContent_ContentPlaceHolderContentTrip_ReportEditControl_TabContainer_TabPanelMedia_MediasUploadControl_UploadAttachmentsImage_1231324875429_1&_UploadControlID=ctl00$ctl00$ContentPlaceHolderContent$ContentPlaceHolderContentTrip$ReportEditControl$TabContainer$TabPanelMedia$MediasUploadControl$UploadAttachments&ContextValue=!3wEWAWQ5poyVsnBArG6lJ6b7R2A4cKwMqA!2!2&_Addon=upload&_AddonGuid=7d30d6df-3548-4280-9ecf-32276f3ce99b

It then goes on to make a request to that url.

So it looks to me the the url rewriting is working fine to this point.

Interesting you mention the string "OK". That might explain an odd behavior Im seeing. I put the a breakpoint of Application_BeginRequest for both a success and fail case. The content length of the failure case is 2 bytes less than the success case (for the same image).

Hi,

I have found the reason, and will provide an update in 3-4 days.

In the fr001270.xml, line 128,URL_CHANGED

the UploadModule use request.RawUrl and try to rewrite the url back to NewUrl="/report/create/area/820/?" ,

but the urlwriter module already would not process it, and then the ASP.NET just report NOT FOUND.

Regards,

Terry

urgent: URL rewriting not supported

Reply Quote

w/o prejudice

Adam,

I downloaded your latest version today.

Every directory in your zip seems to have a different date on the dll contained within, but the most recent seems to be 02/04/09.

The product cannot deal with url rewriting ---- pas en tous. Notwithstanding the de-facto industry standard that all third party asp.net controls deal nicely with url rewriting.

It appears that you have known of this issue for at least three months and yet have failed to address it adequately.

Please address this immediately. I paid 400.00 for this product and if it cannot play nicely with the other kids in the playground I will demand a refund.

I should not have to get into specifics, but, for the application at hand, I redirect all directories, but not files with an extension.

Thanks, Stuart Wachsberg
