Replied to the OTRS ticket and asking for the link of the article that has the issue.

Move this ticket to blocked/waiting and waiting for the response.

Update: the user replied to the OTRS ticket, and looks like the redirected link contains a fragment, which should be handled correctly?

The re-directed url does not give the correct anchor to scroll to. For example in this case it should have been #Dynamic_memory_allocation

Also, it would be better to get this in the link response from mobile-html service than just a url update from page/summary response

Hi @MSantos , @Sharvaniharan !
Does this bug relate to the mobileapps eventually? I've checked the incoming response here.
It seems, that this broken link is building on some other level of the application, because I receive it in response as-is.
Could you point me where to find the source of this bug?

@vadim-kovalenko it looks like Dynamic_memory_allocation is a MediaWiki redirect to Memory_management#DYNAMIC

I'm assuming that the clients want the redirect resolved by the mobile-html, is that right @Sharvaniharan?

@vadim-kovalenko on a second look it looks like we are stripping some custom anchors that should be present on the page, these anchors are created by the Anchor template, like this:

see https://en.m.wikipedia.org/wiki/Memory_management#DYNAMIC source

<span class="anchor" id="DYNAMIC"></span>

I believe that if the anchors are present, the client will be able to work normally.

@MSantos

1. In Java article there is an anchor tag

<a href="/wiki/Dynamic_memory_allocation" class="mw-redirect" title="Dynamic memory allocation">allocated on the heap</a>

2. In Memory management article there is a section 'Dynamic memory allocation' which is result of redirection by link from p.1

3. The 'Dynamic memory allocation' title has span tag with multiple anchors:

<span class="mw-headline" id="Dynamic_memory_allocation">
	<span class="anchor" id="DYNAMIC"></span>
	<span class="anchor" id="HEAP"></span>
	<span class="anchor" id="ALLOCATION"></span>
	Dynamic memory allocation
</span>

As you can see, there are bunch of optional anchors in the 'Dynamic memory allocation' title. So client can use either 'Dynamic_memory_allocation' or 'DYNAMIC' anchor as well.
As per replacing redirect resolving to mobile-html, I need additional clarifications, because I'm not sure what problem it should resolve.
